  1. A pool is filled by two hoses. Hose A fills it in 8 hours and Hose B in 12 hours. How long does it take with both hoses running together?

    Answer: 4.8 hours

    Combined rate = 1/8 + 1/12 = 5/24. Time = 24/5 = 4.8 hours.

  2. A jacket's price was reduced by 30%, and then the reduced price was increased by 20%. What is the overall percent change?

    Answer: −16%

    Start at $100. After 30% decrease: $70. After 20% increase: $84. Net change = −16%.

  3. The length of a rectangle is increased by 25% and the width is decreased by 20%. By what percent does the area change?

    Answer: 0%

    New area = (1.25l)(0.80w) = 1.00lw. The area is unchanged, so the change is 0%.

  4. A boat travels 48 miles downstream in 3 hours and the same distance upstream in 4 hours. What is the speed of the current in mph?

    Answer: 2

    Downstream speed = 16 mph; upstream speed = 12 mph. Current = (16 − 12)/2 = 2 mph.

  5. In 5 years, Maria will be twice as old as she was 4 years ago. How old is Maria now?

    Answer: 13

    x + 5 = 2(x − 4) → x + 5 = 2x − 8 → x = 13.

  6. A 10-pound nut mix costing $6/lb blends cashews ($8/lb) with peanuts ($3/lb). How many pounds of cashews are in the mix?

    Answer: 6

    8c + 3(10 − c) = 60 → 5c = 30 → c = 6 pounds of cashews.

  7. A triangle has a base of 14 cm and a height that is 3 cm less than the base. What is the area in square centimeters?

    Answer: 77

    Height = 14 − 3 = 11 cm. Area = (1/2)(14)(11) = 77 sq cm.
