a craft store has a special offer. for every $90 that customers spend, the store will donate $3 to local schools. how much do customers need to spend for the store to donate $4? first, find the amount needed to donate $1. amount spent ($) 90 amount donated ($) 1 3
Answer
Explanation:
Step1: Find amount per $1 donation
We know that when $90 is spent, $3 is donated. To find the amount needed to donate $1, we divide the amount spent by the amount donated. $90\div3 = 30$
Step2: Find amount for $4 donation
Since it takes $30 to donate $1, to donate $4, we multiply the amount per $1 - donation by 4. $30\times4=120$
Answer:
120
