Calculating the sales price of an item
The sales price of an item is the amount for which a good is being sold. The change in sales price can either be decreased if there are certain percentage or vouchers given on the item or it can be increased if there are additional perks associated with the item.
From the given information, we are being told that the Sales price of every item in a store is 85% of its usual price.
(a) The price of the backpack = 85% × usual price
- If the usual price is $30
Then the sale price of the backpack = 0.85 × 30 = $25.5
(b) The price of the sweatshirt = 85% × usual price
- If the usual price is $18
Then the sale price of the sweatshirt = 0.85 × 18 = $15.3
(b) The price of the soccer ball = 85% × usual price
- If the usual price is $24.80
Then the sale price of the soccer ball = 0.85 × 24.80 = $21.08
