Question

Two plans for reaching a goal are given below.
Plan A: Save $450 over the next 8 weeks by working 9 hours per week at $7.20 per hour.
Plan B: Save $450 over the next 6 weeks by working 15 hours per week at $6.50 per hour.
Which of the following is a true statement?
a.
Only plan A will work for achieving the goal.
b.
Only plan B will work for achieving the goal.
c.
Both plans will work for achieving the goal.
d.
Neither plan will work for achieving the goal.

Answer 1

Plan A: 8 weeks × 9 hrs/week = 72 hrs. 72 × $7.20 = $518.40 (≥ $450)
Plan B: 6 weeks × 15 hrs/week = 90 hrs. 90 × $6.50 = $585 (≥ $450)

So both plans will work. Answer: c.
