The cost of a can ride , y, based on the number of miles driven , x, is represented by
y = 0.80x + 2.50

part a: how expensive is a 7-mile ride ?

part b: how many miles did you travel if the ride cost $13.70 ?

Step-by-step explanation:

y = 0.80x + 2.50

a 7 mile ridex = 7

y = 0.80(7) + 2.50

y = 5.60 + 2.50

y = 8.10 <=== the 7 mile ride cost $ 8.10

the ride cost 13.70y = 13.70

13.70 = 0.80x + 2.50

13.70 - 2.50 = 0.80x

11.2 = 0.80x

11.2 / 0.80 = x

14 = x <=== u travel 14 miles

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
