Linsey bought 3 shirts for $15 each. The sales tax was 7%. Part A. What is the total cost of her purchase including tax? Make sure to show all steps

Answer 1

To find the total cost of her purchase including tax, we need to find the total cost of the shirts before tax and then add the tax amount.

Each shirt costs $15, and she bought 3 shirts, so the total cost of the shirts before tax is 15 * 3 = $<<15*3=45>>45.

The sales tax is 7% of the total cost of the shirts, so the tax amount is 7% * $45 = $3.15.

To find the total cost of her purchase including tax, we add the total cost of the shirts and the tax amount: $45 + $3.15 = $<<45+3.15=48.15>>48.15. Answer: \boxed{48.15}.

Answer 2

Part B Linsey has $50.00. How much change will she receive after buying her 3 shirts?

Answer 3

To find out how much change Linsey will receive after buying her 3 shirts, we need to subtract the total cost of her purchase from the amount of money she has.

The total cost of her purchase, including tax, is $48.15.

To find the change she will receive, we subtract the total cost from the amount of money she has:
$50.00 - $48.15 = $<<50-48.15=1.85>>1.85.

Linsey will receive $1.85 in change. Answer: \boxed{1.85}.
