Jonah is purchasing a car that is on sale for 15% off. he knows the function that represents the sale price of his car is c(p) = 0.85p, where p is the original price of the car. he also knows he has to pay 9% sale's tax on the car. the price of the car with tax is f(c) = 1.09c, where c is the sale price of the car.

determine the composite function that can be used to calculate the final price of jonah's car by solving for f[c(p)].

f[c(p)] = 0.9265cp
f[c(p)] = 0.9265p
f[c(p)] = 1.94cp
f[c(p)] = 1.94p

f[c(p)] = 0.9265p

Step-by-step explanation:

Given: Jonah is purchasing a car that is on sale for 15% off. He knows the function that represents the sale price of his car is , where p is the original price of the car.

He also knows he has to pay 9% sale's tax on the car. The price of the car with tax is , where c is the sale price of the car.

Now, the composite function that can be used to calculate the final price of Jonah's car is given by :-

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
