Question

whitney went to the hobby store. she bought 3 model airplanes for $4 each. she received $8 in change. how much money did she start with?

Answer 1

She started with $20 :)

Explanation:

If each model airplane was worth $4, and she bought 3. That means she bought 12 dollars worth of airplanes. If she received 8 dollars back, it means she started with $20.

Here's an equation explanation if this is better:

3 X 4 =12

12+ 8= 20

(12 dollars for how much she spent, 8 dollars change, 20 dollars to start with)

Hope this makes sense!! :)
