Blake and James are planning to go on a trip. Blake already has some money saved. She earns $96 more by working overtime. James

Blake saved $\bold{\$ 433.80}$

Option - A

<u>SOLUTION: </u>

Given, Blake and James are planning to go on a trip.

Blake already has some money saved.

Let the amount saved by Blake be $\$ n$ .

She earns $\$96$ more by working overtime.

Then, total amount by Blake $=\$(n+96)$

James has $\$ 53$ more than 4 times the amount of money that Blake has saved.

Then, total amount by James will be $\$ 53+4 \times \$ n=\$(4 n+53)$

If they have $\$2,318$ in all, we have to find how much money had Blake originally saved

Now, total amount = $\$2318$

$\begin{array}{l}{\rightarrow \text { Amount by Blake }+\text { amount by James }=2318} \\\\ {\rightarrow \mathrm{n}+96+4 \mathrm{n}+53=2318 \rightarrow 5 \mathrm{n}+149=2318 \rightarrow 5 \mathrm{n}=2318-149 \rightarrow 5 \mathrm{n}=2169 \rightarrow \mathrm{n}=433.8}\end{array}$

The first step for solving this expression is to distribute $\frac{3}{8}$ through the first set of parenthesis.
$( \frac{3}{8}x - \frac{3}{8})$ × (x - 9)
Now use the FOIL method to multiply each term in the first parenthesis by each term in the second parenthesis. This will look like the following:
$\frac{3}{8}$ x × x - $\frac{3}{8}$ x × 9 - $\frac{3}{8}$ x - $\frac{3}{8}$ × (-9)
Remember that multiplying two negatives together equals a positive,, so the expression changes to:
$\frac{3}{8}$ x × x - $\frac{3}{8}$ x × 9 - $\frac{3}{8}$ x + $\frac{3}{8}$ × 9
Calculate the product of all of the sets of multiplication to make the expression become:
$\frac{3}{8}$ x² - $\frac{27}{8}$ x - $\frac{3}{8}$ x + $\frac{27}{8}$
Lastly,, calculate the difference of - $\frac{27}{8}$ x - $\frac{3}{8}$ x to find your final answer.
$\frac{3}{8}$ x² - $\frac{15}{4}$ x + $\frac{27}{8}$
Let me know if you have any further questions.
