Answer:
Tax= $4
Total payed: $44
Step-by-step explanation:
It´s very simple, you just have to calculate the tax by multiplying the cost of the purchase by the percentage, you just do a rule of thirds:
Now we just clear the X to solve for the value of the 10%:
So we know that the tax is 10% of $40 which is $4.
The total payed is calculated by adding up the cost plus the taxes:
Total payed= Cost+Taxes
Total payed= $40+$4
Total payed: $44
