Answer:
$69
Step-by-step explanation:
Given the amount of money each girl spent based on the number of hours they were shopping modeled by the function p(x) = 3x4 + 2x3 − 4x2 + 21
To get how much they spend together if each go shopping for 2hours, we will substitute x = 2 into the given function as shown:
p(2) = 3(2)⁴ + 2(2)³ − 4(2)² + 21
p(2) = 3(16) + 2(8) − 4(4) + 21
p(2) = 48 + 16 − 16 + 21
p(2) = 48+21
p(2) = 69
Therefore they spend $69 together

<h2>He could use the medium box.</h2>
Step-by-step explanation:
Notice that the umbrella is 37.5 inches long.
If you observe, each box doesn't have 37 inches wide, however, they are tridimensional figures, which means they have a certaing height.
So, the smalle box is too small to fit the umbrella.
But, the medium box is perfect, because it has 27 inches wide and 27 inches height, which is enough to fit the umbrella. These are the best dimensions to send the umbrella.
Therefore, the medium box is the answer, the one that has dimensions 27x14x27.
