Answer:
50
Step-by-step explanation:
cost function : 35 + 0.2m = 45
35 = fixed cost
0.2 = variable cost
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
Variable costs are costs that vary with production
m = miles driven
combine like terms
0.2m = 45 - 35
0.2m = 10
m = 50
