Jonathan knit some scarves to sell at a local arts-and-crafts show. The function r(x)=13x models the amount of money, in dollars, he brings in by selling x scarves. The function c(x)=6x models the cost, in dollars, for Jonathan to produce x scarves. It also costs Jonathan $58 to get a booth at the show. Which of the following functions p(x) models his profit for selling x scarves?

The answer is A.  

Step-by-step explanation:

since $12 is the amount of money he gets from selling scarves you have to subtract $2 from that because that's the amount of money he losses to make the scarves. then you have to subtract $45 because he had to pay for the booth so the answer is P(x) = 10x - 45

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
