We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m
Now, let's subtract both sides by 11
We now have the value of m.
The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.
Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Answer:
$600
Step-by-step explanation:
Simple Interest Rate: A = P(1 + RT)
A Total Value
P Principle
R Rate
T Time
__________________________________________________________
<h2>Step 1: Insert Values </h2><h2> </h2>Let's plug the info we have into the formula:
A = 4000(1 + 0.05(3))
A = 4000 + 4000(0.15)
A = 4000 + 600
A = 4600
__________________________________________________________
<h2>Step 2: Finding the Interest</h2><h2 />So the total value she ends up with $4600, but we want to find the extra value, or interest, she has to pay.
To find this we subtract the principle from the new value:
4600 - 4000 = 600
Liz has to pay $600.
