Lydia's mom earns $4 in rewards for every $75 she spends at the grocery store. If she earned $44 in rewards last month, how much did she spend at the store?
Take baseline amount of 75 dollars and divide it by 4. This will get you to the answer 11.25. Use 11.25 and multiply it by what she received in rewards. 11.25 times 44 equals....495!
