Question

Timothy has $500. He spends $50 each week on

groceries. Write an equation to find the total amount
of money he has left, y, after x weeks have passed.

Answer 1

It takes 10 weeks to spend each $500

Explanation:

If he spend $50 each week on groceries, we can say that he spend $100 on groceries every two weeks

To make it to 500 dollars we would have to use the equation 100x5.

This equals to 500

We could also do 100 plus 100 plus 100 plus 100 plus 100.
