Answer:
$176
Explanation:
Janelle and her best friend Carmen go shopping. the function p(t) = 5x^4 - 3x^3 + 2x^2 + 24 represents how much money each girl spent based on the number of hours they were shopping. If Janelle and Carmen each go shopping for 2 hours how much money did they spend together.
$58
$62
$176
$124
p(t) = 5x^4 - 3x^3 + 2x^2 + 24
Solve when x = 2 hours
p(t) = 5x^4 - 3x^3 + 2x^2 + 24
= 5(2)^4 - 3(2)^3 + 2(2)^2 + 24
= 5(16) - 3(8) + 2(4) + 24
= 80 - 24 + 8 + 24
= $88
how much money did they spent together?
= $88 × 2
= $176
They both spent $176 altogether
