If Sally has 3 apples and Bob gives her 2 more, how many apples does Sally have now?

In this word problem, Sally starts with 3 apples, and Bob gives her 2 more. To find the total number of apples, we simply add the initial amount with the additional apples given by Bob.

So,

Sally's initial apples = 3

Apples given by Bob = 2

Total apples = Initial apples + Apples given by Bob

Total apples = 3 + 2 = 5

Therefore, Sally now has 5 apples.

This type of problem falls under basic algebraic expressions, and it's important for Grade 8 students to grasp these foundational concepts.
