Question

gamal spent $12.50 at the book store. the difference between the amount he spent at the video game store and the amount he spent at the book store was $17. the equation ( d - 12.50 = 17 ) can be used to represent this situation, where ( d ) is the amount gamal spent at the video game store. which equation is an equivalent equation that can be used to find the amount gamal spent at the video game store?

• ( d = 17 - 12.50 )
• ( d = 17 + 12.50 )
• ( d - 12.50 = -17 )
• ( d + 12.50 = 17 )

Explanation:

Step1: Recall equation-solving rules

To solve for \( d \) in \( d - 12.50 = 17 \), we use the addition property of equality. We add \( 12.50 \) to both sides.

Step2: Apply the property

Adding \( 12.50 \) to both sides of \( d - 12.50 = 17 \) gives \( d - 12.50 + 12.50 = 17 + 12.50 \), which simplifies to \( d = 17 + 12.50 \).

Answer:

\( d = 17 + 12.50 \) (corresponding to the option "d = 17 + 12.50")
