Part 6 easy but hard math asap

Equation: 89≥0.2x+35

270 miles

Step-by-step explanation:

35 is the starting amount (y intercept)

0.2 is the rate of change (slope)

the slope formula is y=mx+b

(m) is slope (b) is y intercept

y=0.2x+35

our y is total cost and x is our miles driven

apply the $89 max amount spent

89≥0.2x+35

now solve

subtract 35 from each side

54≥0.2x

multiply each side by 5

270≥x

Amelia can drive at most 270 miles
