Leonard wants to save $100 in the next 2 months. He knows that in the

second month, he will be able to save $20 more than the first month.

How much should he save each month?

Ok so 100-20 that would get you to 60 and it's between two months, one month you would have to save 60 and 40 the other because when you think about it, you would have 40 and 40 if it was the same amount each month but because you have an extra 20 the second month, you add the 20 to the 40 making your answer 40 and 60
