Janelle and her best friend Carmen go shopping. The function p(t) = 5x4 − 3x3 + 2x2 + 24 represents how much money each girl spe

Arlecino [84]

Answer:

$176

Step-by-step explanation:

The function $p(x) = 5x^4-3x^3 + 2x^2 + 24$ 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

$p(x)=5\cdot 2^4-3\cdot 2^3+2\cdot 2^2+24=5\cdot 16-3\cdot 8+2\cdot 4+24=80-24+8+24=88$

Thus, Janelle spent $88.

Carmen goes shopping for 2 hours, then x=2 and

$p(x)=5\cdot 2^4-3\cdot 2^3+2\cdot 2^2+24=5\cdot 16-3\cdot 8+2\cdot 4+24=80-24+8+24=88$

Thus, Carmen spent $88 too.

Together they spent

$88+$88=$176

rusak2 [61]

In order to find the answer, divide distance in afternoon from in the morning.
It would be: = 4 1/8 / 1 / 7/8
= 33/8 / 15/8

We can re-write it as:
33/8 * 8/15
= 33/15

In short, Your Answer would be 33/15 or 2.2 times
