Question

Ronnie operates a lawn-care service. On each day, the cost of mowing the first lawn is $15, the cost of mowing the second lawn is $25, and the cost of mowing the third lawn is $40. His producer surplus on the first three lawns of the day is $100. If Ronnie charges all customers the same price for lawn mowing, that price is:__________a. $25
b. $30
c. $36
d. $45

Answer 1

Answer:

. $45

Explanation:

Let X be the amount of equal charges per customer.

Therefore,

X-12+X-25+X-40+X=100.

4X-77=100

4X=177

X=44.25

Approximately $45

Answer 2

Answer:

$60

Explanation:

Producer surplus is defined as the difference between the price that a producer is willing to charge for its products or services, and their actual selling price.

let S = supplier surplus

(S - $15) + (S - $25) + (S - $40) = $100

3S - $80 = $100

3S = $180

S = $180 / 3 = $60
