The revenue from selling x hats is r(x)=18x the cost of buying x hats is c(x)=8x+30. the profit from selling x hats is p(x)=r(x)-c(x)
write a function for p(x), the profit from selling x hats

The correct answer is c) p(x)=10x-30

Step-by-step explanation:

The answer is given in the question, you just have to replace r(x) and c(x) in the profit formula.

p(x)=r(x)-c(x)

p(x)=18x-(8x+30)

Solving=

p(x)=10x-30

Be careful with the signs

So the correct answer would be option :

c) p(x)=10x-30

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
