Question

rachel read 3 more books than topher did over their summer vacation. if rachel read 7 books, how many books did topher read? choose 1 answer: a 7 b 10 c 3 d 4

Explanation:

Step1: Define variables

Let \( T \) be the number of books Topher read, and \( R = 7 \) be the number of books Rachel read.

Step2: Set up equation

We know \( R=T + 3 \) (Rachel read 3 more than Topher).

Step3: Solve for \( T \)

Substitute \( R = 7 \) into the equation: \( 7=T + 3 \). Subtract 3 from both sides: \( T=7 - 3=4 \).
