Shawna and her best friend Keisha go shopping. The function p(t) = 3x4 + 2x3 − 4x2 + 21 represents how much money each girl spen

Komok [63]

Shawna and her best friend Keisha together spend $ 138

<h3>Solution:</h3>

Given that, Shawna and her best friend Keisha go shopping.

The function given for money each girl spent based on the number of hours they were shopping is:

$p(t)=3 x^{4}+2 x^{3}-4 x^{2}+21$

Find the amount of money that each girl spent

For t = 2 hours

$\begin{array}{l}{\mathrm{p}(2)=3(2)^{4}+2(2)^{3}-4(2)^{2}+21} \\\\ {\mathrm{p}(2)=3 \times 16+2 \times 8-4 \times 4+21} \\\\ {\mathrm{p}(2)=48+16-16+21} \\\\ {\mathrm{p}(2)=69}\end{array}$

Find the amount of money that they spend together

Multiply by 2 the amount of money that each girl spent

$2 \times 69 = 138$

In one row there are 36 spruce trees. 14 of these are blue spruce.
This means that in a row 36-14=22 are not blue spruce.

There are a total of 9 rows with 22 not blue spruce trees each, so in total there are:

$9\cdot22=198$ not blue spruce trees.
