Answer:
B. Collect like terms
Step-by-step explanation:
The first step is to subtract from each side of the equation, and we have the following
We can see that on the left side of the equation we have <u>like terms</u> (the two terms containing x)
so the next step is to combine or collect those like terms and
to simplify the expression:
We are not distributing or eliminating the (because there is still a term with x on the right side), nor are we completely isolating the
yet.
What was done in this step was to collect like terms.

Answer:
<em>Martin saved $75 on the television because of the sale</em>
Step-by-step explanation:
<u>Equations</u>
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x = = 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale
