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

$60

Explanation:

The computation of price is shown below:-

Producer Surplus = Price paid by consumers - Production cost

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

$100 = Price - $80

Price for all = $100 + $80

= $180

Price Per consumer = Price for all ÷ First three lawns

= $180 ÷ 3

= $60

Therefore, for computing the price per consumer we simply divide first three lawn by price for all.
