Create and Interpret Math Equations with Variables

1. Sarah has some apples. Let 'a' represent the number of apples she has. If she buys 5 more apples, how can we write an equation to show the total number of apples Sarah has now?

• total_apples = a / 5

• total_apples = a + 5

• total_apples = a * 5

• total_apples = a - 5
