Question

Sarah is purchasing a shirt that is on sale for 20% off. She knows the function that represents the sale price of her shirt is s(p) = 0.8p, where p is the original price of the shirt. She also knows she has to pay 7% sale's tax on the shirt. The cost of the shirt with tax is c(s) = 1.07s, where s is the sale price of the shirt.

Determine the composite function that can be used to calculate the final price of Sarah's shirt by solving for c[s(p)].

Answer 1

c[s(p)] = 0.856p
c[s(p)] = 0.856sp
c[s(p)] = 1.87p
c[s(p)] = 1.87sp

Answer 2

Choose the correct simplification of the expression f to the 6th power times h to the 9th power all over f to the 3rd power times h to the 7th power.

f12h6
1 over f to the 12th power times h to the 6th power
f3h2
1 over f to the 6th power times h to the 6th power

Answer 3

since s(p) is to find discount price you have to have that inside parentheses then outside of that u put c for tax

Answer 4

d?

Answer 5

now how do u get 1.07 of .8

Answer 6

1.87

Answer 7

no

Answer 8

0.856

Answer 9

u dont add u multiply to get .856
