Step-by-step explanation:
The function
represents how much money each girl spent based on the number of hours they were shopping.
Janelle goes shopping for 2 hours, then x=2 and
![p(x)=5\cdot 2^4-3\cdot 2^3+2\cdot 2^2+24=5\cdot 16-3\cdot 8+2\cdot 4+24=80-24+8+24=88](https://tex.z-dn.net/?f=p%28x%29%3D5%5Ccdot%202%5E4-3%5Ccdot%202%5E3%2B2%5Ccdot%202%5E2%2B24%3D5%5Ccdot%2016-3%5Ccdot%208%2B2%5Ccdot%204%2B24%3D80-24%2B8%2B24%3D88)
Thus, Janelle spent $88.
Carmen goes shopping for 2 hours, then x=2 and
![p(x)=5\cdot 2^4-3\cdot 2^3+2\cdot 2^2+24=5\cdot 16-3\cdot 8+2\cdot 4+24=80-24+8+24=88](https://tex.z-dn.net/?f=p%28x%29%3D5%5Ccdot%202%5E4-3%5Ccdot%202%5E3%2B2%5Ccdot%202%5E2%2B24%3D5%5Ccdot%2016-3%5Ccdot%208%2B2%5Ccdot%204%2B24%3D80-24%2B8%2B24%3D88)
Thus, Carmen spent $88 too.
Together they spent
$88+$88=$176
