Lindsay bought 3 shirts for $15 dollars each. the sales tax in Indiana is 7%.
What is the total cost of her purchase, including tax? Show all steps.
To calculate the total cost of Lindsay's purchase, including tax, we need to find the total cost of the shirts and add the sales tax.
The total cost of the shirts is found by multiplying the cost of each shirt by the number of shirts.
3 shirts * $15 per shirt = $<<3*15=45>>45
Now, we need to find the sales tax amount by multiplying the total cost of the shirts by the sales tax rate.
$45 * 0.07 (7%) = $<<45*0.07=3.15>>3.15
Finally, we add the sales tax amount to the total cost of the shirts to find the total cost of the purchase.
$45 + $3.15 = $<<45+3.15=48.15>>48.15
Therefore, the total cost of Lindsay's purchase, including tax, is $48.15.
Lindsay has 50 dollars. How much change will she receive after buying her 3 shirts?
To determine how much change Lindsay will receive after buying the 3 shirts, we need to subtract the total cost of the purchase from the amount of money she has.
From the previous calculation, we found that the total cost of the purchase, including tax, is $48.15.
To find the amount of change Lindsay will receive, we subtract the total cost from the amount of money she has:
$50 - $48.15 = $1.85
Therefore, Lindsay will receive $1.85 in change after buying her 3 shirts.
