Question

10. Ann is moving from Houston to McKinney and rented a truck from U-Move truck rentals. The cost of a one-day truck rental is given by
C(m) = 0.3m + 50

where m is the number of miles driven. If the cost of the truck rental is $131.00, how many miles did Ann drive the rental truck?
300 miles
230 miles
280 miles
270 miles

Answer 1

131 = 0.3m + 50

Answer 2

can you solve for m ?

Answer 3

131=.3m+50
81=.3m
810=3m

Answer 4

no

Answer 5

subtract 50 from both sides
131-50 = 0.3m + 50 - 50
81 = 0.3m
divide both sides by 0.3
m = 270
