The total cost was $8.80 before tax.
Step-by-step explanation:
The prices of items;
$3.25, $0.55, $2.95, and $4.25
Total price = Sum of all prices
Total price = $3.25 + $0.55 + $2.95 + $4.25
Total price = $11.00
Sale = 20% off
Discount = 20% of total price
Discount = [tex]\frac{20}{100}*11[/tex]
Discount = [tex]\frac{220}{100}= \$2.20[/tex]
Total cost of items bought = Total price - Discount
Total cost of items bought = 11.00 - 2.20 = $8.80
The total cost was $8.80 before tax.
