Question

Shawna and her best friend Keisha go shopping.

Answer 1

Answer:

138

Step-by-step explanation:

p(x) = 3x^4 + 2x^3 − 4x^2 + 21

Let x = 2

p(2) = 3*(2)^4 + 2*(2)^3 − 4*(2)^2 + 21

       = 3*16+2*8-4*4+21

       =48+16-16+21

        = 69

This is per girl

There are 2 girls

2 * 69

138
