Milan puts 1/4 of her lawn mowing money in savings and uses 1/2 of the remaining money to pay back her sister. If she has $15, how much did she have at first.
If we add up how much money Milan spent, she would've spend 3/4 of her money already. That would mean 1/4 is equal to $15. Being only 1/4, we would need to multiply the value by 4 to achieve the total.
