Answer:
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
