Let's carefully analyze and solve the given problem step-by-step.
The equation provided is:
[tex]\[ d - 12.50 = 17 \][/tex]
Our goal is to find the amount Gamal spent at the video game store, which is represented by [tex]\( d \)[/tex]. To do this, we need to isolate [tex]\( d \)[/tex] on one side of the equation. Here's how we do it:
1. Starting with the equation:
[tex]\[ d - 12.50 = 17 \][/tex]
2. Isolate [tex]\( d \)[/tex] by adding [tex]\( 12.50 \)[/tex] to both sides of the equation:
[tex]\[ d - 12.50 + 12.50 = 17 + 12.50 \][/tex]
3. Simplifying the equation:
[tex]\[ d = 17 + 12.50 \][/tex]
So, the equivalent equation that can be used to find the amount Gamal spent at the video game store is:
[tex]\[ d = 17 + 12.50 \][/tex]
Therefore, the correct equivalent equation is:
[tex]\[ d = 17 + 12.50 \][/tex]
