Respuesta :

Answer:

• (a)$6.30

,

• (b)$9.50

Explanation:

Part A

If the carwash wants to make a profit of about $1000 to pay their bills, from the graph, they need to charge just a little above $6.

The closest is $6.30

Note that you also get a value close to $13.00 but increasing the price above the value of x at maximum is not a good choice.

Part B

The maximum point of the graph is at (9.5, 1102.5).

Thus, in order to make the most profit, the carwash should charge $9.50 per service.
