A driver travels for 4 hours at 88 miles per hour during which his car gets 40 miles per gallon of
gasoline. He is paid $0.60 per mile, and his only
expense is gasoline at $3 per gallon. What is his net
rate of pay, in dollars per hour after this expense?

Total miles: 4 hours x 88 miles per hour = 352 miles

Pay = 0.60 per mile x 352 miles = $211.20

Gallons of gas used = 352 miles / 40 miles per gallon = 8.8 gallons

Cost of gas  = 8.8 gallons x 3 per gallon = $26.40

Net pay = amount paid - amount spent

Net pay = 211.20 - 26.40 = 184.80

$184.80

10 - 3x

Step-by-step explanation:

Since the number 10 is decreased by 3x, that would mean the expression is 10 - 3x.

Hope this helped!
