Answer:
The expression is 1/16 when x = -2, The expression is 64 when x = 3.
Step-by-step explanation:
Part A)
<u>Evaluate 4^x for x = -2. Write your answers in simplest form:</u>
= 4^(-2)
= 1/4^2 ( 1 / 4 * 4)
= 1/16
Part B)
<u>Evaluate 4^x for x = 3. Write your answers in simplest form:</u>
=4 ^ 3
= 4 * 4 * 4
= 16 * 4
= 64

The person that saves the most money every month is given as Jerry
<h3>How to solve for the savings</h3>
We have to solve for 35 percent of 5 dollars
= 0.35 * 45
= 1.75
This is the amount that Tom saves
The question tells us that Jerry spends 2/5 of his, hence he would save 2/5
then we have 2/5 * 5
= 2
Therefore we have that Jerry is the one that saves the most money because he saves 2 dollars.
Complete question
Tom and Jerry both earn the same monthly salary.
Each month
Tom saves 35% of his salary.
Jerry spends 3/5
of his salary and saves the rest of his salary.
Work out who saves the most money each month.
You must show your working.
