Question

Mike paid $2.94in sales tax on an item that cost $42.00 before tax. At that rate how much would he pay in sales tax for an item that costs $58.00 before tax ?

Answer 1

He would pay $4.06 sales tax for an item costs $58.00 before tax.

Explanation:

Given:

Mike paid $2.94 in sales tax on an item that cost $42.00 before tax.

Now, at that rate find the sales tax for an item that costs $58.00 before tax.

So, we find the rate:

Sales tax rate = sales tax on item / cost of item before tax × 100

`=(2.94)/(42) * 100`

`=(294)/(42)`

`=7\%`

Now, we get sales tax on item costs $58.00:

`Sales\ tax=7\%\ of\ \$58.00`

`Sales\ tax=(7)/(100)* 58`

`Sales\ tax=(406)/(100)`

`Sales\ tax=\$4.06`

Therefore, he would pay $4.06 sales tax for an item costs $58.00 before tax.
