Question

Greg and Josh want to go whitewater rafting in 3 weeks. Josh is able to save the $480 he needs to go on the trip by saving the pay he received for 5 hours of work each week. Greg must save 8 hours worth of pay each week in order to have enough money. How much more money does Josh make than Greg? a. $10 b. $12 c. $14 d. $20

Answer 1

Answer: Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Amount Josh is able to save = $480

Number of hours of work each week = 5

Number of weeks = 3

So, Amount Josh makes is given  by

$\dfrac{480}{5\times 3}\\\\=\dfrac{480}{15}\\\\=\ 32$

Similarly,

Number of hours of work each week by Greg = 8

Number of weeks = 3

So, Amount Greg makes is given by

$\dfrac{480}{3\times 8}\\\\=\dfrac{480}{24}\\\\=\ 20$

More amount of money that Josh make than Greg is given by

$32-20\\\\=\ 12$

Hence, Option 'b' is correct.

Answer 2

Josh = 480/15 or 32

Greg = 480/24 or 20

Let J = how much more Josh has than Greg.

J = 32 - 20

Solve for J to find your answer.
