Each bag costs $4.7108, so 4 bags cost $18.8435.
Including a sales tax of 8.75%, 4 bags cost $20.4923.
Step-by-step explanation:
Step 1; The original cost of 4 bags was $28.99. If the store had a discount of 35%, then we need to calculate how much 35% of $28.99 is,
35% of $28.99 = [tex]\frac{35}{100}[/tex] × 28.99 = $10.1465,
so price after discount = $28.99 - $10.1465 = $18.8435.
Step 2; To calculate the cost of a single bag, we divide the number of bags by the cost.
Cost of a single bag = [tex]\frac{18.8435}{4}[/tex] = $4.7108. So each bag costs $4.7108 after the 35% discount.
Step 3; There is a sales tax of 8.75% on the total amount. So we also need to calculate how much 8.75% of $18.8435 is.
8.75% of $18.8435 = [tex]\frac{8.75}{100}[/tex] × 18.8435 = $1.6488.
So total price with tax = $18.8435 + $1.6488 = $20.4923.
