Suppose an item cost $40. What is the total amount you would pay if there is a 6% tax?

Question

I need the answer and the work so I can help my kid

Answer 1

6% = 0.06

tax = 0.06 times $40 = .06(40) = .6(4) = 2.4 = $2.40

or just punch the numbers into a calculator: .06 x 40= 2.4 dollars

total cost = $40 + $2.40 = $42.40
