Julian gave money to two of his favorite charities. He gave 50% more money to the Clean Air Fund than to the Library Fund. If Julian gave $15 to the Clean Air Fund, how much money did he give altogether?
To find the answer you need to add 50% to 15 and to that is to simply add 5 to 15 which is 20.
and since it wants to know how much money it gave altogether add 20 + 15 which is 35.
So 35 is your answer
Let x be the amt given to the Library Fund
Then 1.5x was given to Clean Air Fund = 15
1.5x = 15
x = 15 /1.5 = $10 to Library Fund
Total given = 10 + 15 = $ 25
