On number 12 I need hell

1,600 dollars

Step-by-step explanation:

The easiest way to solve it is to find the dollar for 1 percent.

Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.
