$15.12

Step-by-step explanation:

You just need to find 84% of 18 which is 15.12. what you do is you convert the percent into 0.84 and multiply is by the original price which is 18.

84%=0.84

0.84 times 18 = 15.12

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
