Look at side AB.
The slope is -1/4.

Look at side BC.
The slope is 4.

The product of -1/4 and 4 is -1. That makes segments AB and BC perpendicular and angle B a right angle. That makes triangle ABC a right triangle.

Let S be the amount in a savings account.
Let m be the number of months.

General equation
S = 132 + 27m

Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321

Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.
