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

We will find the rate of Greg and Josh earning money that is the amount of money they receive per unit time (hour)

Since the trip is in 3 weeks,

Number of hours Josh worked = 3 weeks * (5 hours/week) = 15 hours

Number of hours Greg worked = 3 weeks * (8 hours/week) = 24 hours

Josh’s rate = $480/15 hrs = $32/hr

Greg’s rate = $480/24 hrs = $20/hr

Therefore

Josh makes $12/hr more than Greg
