Answer:
About $3.20 in tax, $43.20 total
Step-by-step explanation:
First you want to put the percentage into a decimal, 0.08. Then you would multiply the $40 by 0.08 (tax) to get the amount of tax ($3.20). Then to find the total amount, you could either add $3.20 and $40 together or you could multiply $40 by 1.08 (this accounts for both the item and the tax) to get $43.20.
