Answer: $3.52 (Three dollars and fifty two cents)
Explanation: First you have to convert the percentage into a decimal. Taking 7% and moving the decimal to the left twice. You’re left with .07 (D). Multiply the .07 with the original price $3.29 (OP). Now you know your tax- .2303. (T)
(D)*(OP)=(T)
To complete the problem add your tax (.2303) to the original price. In this case you’ll get $3.52, aka your answer (A).
(T)+(OP)=(A)
