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