Question

George has to pay $30 in taxes for every $100 that he earns. Last summer, he earned $3680. How much did he pay in taxes?(must use direct proportion) pleaseee help

Answer 1

$1,140

Explanation:

Step 1: Set up a fraction and solve (We are doing this to make it simpler to solve. So let us use "x" to represent how much he paid in taxes. )

`(30)/(100)=(x)/(3680)`

Step 2: Solve; Divide the given values (The given values are 100 over 30. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.3 once divided)

`(30)/(100)`

Cancel both zeros

`(30)/(100)\\\\= (3)/(10)`

Divide

`(3)/(10)\\\\= 3 / 10\\\\= 0.3`

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)

`0.3\\\\0.3 * 3680\\\\=1140`

Therefore, George paid 1140 dollars in taxes last summer.
