Answer:
Joy spent a total of $23.38 when considering the 7.5% sales tax.
Explanation:
Total cost without tax:
Ticket price: $9
Popcorn price: $7.50
Soda price: $5.25
Add these prices together: $9 + $7.50 + $5.25 = $21.75
Sales tax amount:
Sales tax rate: 7.5%
Multiply the total cost without tax by the sales tax rate (as a decimal):
$21.75 * 0.075 = $1.63
Total amount spent (including sales tax):
Add the total cost without tax and the sales tax amount:
$21.75 + $1.63 = $23.38
