Question

You spent 1/2 of your money at the theater and 1/4 at an arcade. you have $17.50 left. How much money did you originally have?

Answer 1

I got 70 because 17.5 is 1/4 of 70 and 3/4 of the money was spent.

Answer 2

You basically add 17.50+17.50=35 and add 35+35=70, reason being is because the 35 is the 1/2 and 17.50 is the 1/4 so 70 is your answer
