Answer:
marginal cost is 15 cents
Explanation:
given data
car rent = $29.95
distance d1 = 150 miles
cost = 15 cents per miles
distance d2 = 200 miles
to find out
marginal cost
solution
first we find here cost for driving d2
cost for 150 to 200 miles = 15 × 50
cost for 150 to 200 miles = 750 cents = $7.5
so
cost for driving d2 = $7.5 + $29.95
cost for driving d2 = $37.45
so
marginal cost will be
marginal cost = change in cost / chance in distance
marginal cost = 37.45 - 39.95 / ( 200-150)
marginal cost = 7.5 / 50 = 0.15
marginal cost is 15 cents
