Exam 1 Review

Practice, in ALEKS order

These run in the same order as the ALEKS Exam Review, so item 4 here is question 4 there. Work down the list, then sit the review once.

• 1

  Question 1. Percent of a total, without a calculator

  Question 1 Finding a percent of a total without a calculator →

  ALEKS names this one "without a calculator" and picks numbers that decompose in your head. Question 16 is the calculator version and a different ALEKS topic.

  Question 2. Choosing between a percent discount and a flat rebate

  Question 2 Choosing between a percent discount and a flat rebate →

• 3

  Question 3. Two successive percent changes applied in sequence

  Question 3 Applying two successive percent changes →

  The single most valuable question on the paper. An 80 percent markup is not the same as 10 percent then 70 percent, and students reliably add them.

• 4

  Question 4. Original amount from a percent decrease and the result

  Question 4 Finding the original amount after a percent change →

  You are told the size of the CHANGE and must work out that 74% survived a 26% fall. Question 5 hands you that figure.

• 5

  Question 5. Original price from the sale price and the percent it represents

  Question 5 Finding the original price given the sale price and percent →

  Reads "is 74% of", not "74% off", so the decimal is handed to you. That missing inference is what makes this a different ALEKS topic from question 4.

  Question 6. Word problem involving a U.S. Customary length conversion

  Question 6 Word problem involving a U.S. Customary length conversion →

  Divides a total by the number of laps and then converts, which is the reverse of the topic review question this used to point at.

• 7

  Question 7. Converting between units of volume

  Question 7 Converting between U.S. Customary units of volume →

• 8

  Question 8. Area with U.S. Customary conversions, whole units, and cost

  Question 8 Area with U.S. Customary conversions, rounded up, and costed →

  Dimensions arrive in inches and the coverage is in square feet, so the conversion comes first. Squaring a length squares the factor: 1 ft2 is 144 in2, not 12.

• 9

  Question 9. Area with conversions between systems, whole units, and cost

  Question 9 Area with conversions between systems, rounded up, and costed →

  The cross-system twin of question 8: feet to centimetres, factor 30.48. ALEKS says not to round the intermediate steps here, and on this one that can move the bag count.

  Question 10. Cross-system weight conversion feeding a dosage rate

  Question 10 Converting weight across systems to compute a dosage →

• 11

  Question 11. Converting between Fahrenheit and Celsius

  Question 11 Converting between Fahrenheit and Celsius →

  Fahrenheit to Celsius with a negative reading and a rounding instruction. Both are the difficulty, and the topic review question runs the other direction without either.

• 12

  Question 12. Surface area with openings subtracted, then material cost

  Question 12 Finding paintable wall area and costing the paint →

  The largest single build on this exam: four walls, a window given in inches, a door, two side windows, then bags and cost. Needs a diagram.

• 13

  Question 13. Metric conversion with decimal values: two-step problem

  Question 13 Metric conversion with decimal values: two-step problem →

  Metric MASS, not length. This was being served by a U.S. Customary length page that it also shared with question 6.

• 14

  Question 14. Converting between compound units: advanced

  Question 14 Converting between compound units: advanced →

  Both halves of the rate convert, and in opposite directions: miles to feet multiplies, hours to seconds divides. The topic review question changes the numerator only. Question 15 teaches choosing the factor but stops before running the chain.

  Question 15. Selecting the correct factor inside a conversion chain

  Question 15 Selecting the correct conversion factor →

• 16

  Question 16. Percent of a total, real-world situations

  Question 16 Finding a percent of a total in a real-world situation →

  Awkward percent, awkward total, and an explicit instruction to round. Same formula as question 1, different job.

  Practice ready
• 17

  Question 17. Finding the sale price given the original price and percent discount

  Question 17 Finding the sale price given the original price and percent discount →

  Was pointing at the topic review question, which applies the same percent decrease to an investment balance rather than a price. Same arithmetic, different story.

• 18

  Question 18. Percent increase given two values

  Question 18 Finding the percent change given two values →

  Reverse of question 17: the percent is the unknown.

  Question 19 Building a linear equation from a description, then using it →
