Answer:
Step-by-step explanation:
Cost function: Fixed costs+ Variable costs
In this case Justin will have to pay $750 to star the business, this is his fixed cost. And then, he will have to pay $1,50 per each lawn, this is his variable cost because it depends on the number of lawns he sells.
C(x)= $750+$1,50x
Revenue function (R(x)):
R(x)= Price * Number of units sold (x)
R(x)= $35*x
Profit function ((P(x))= Revenue function (R(x))-Cost function (C(x))
P(x)= $35x- [$750+$1,50x]
P(x)= $33,5-$750
