never mind i figued it out
To find the sale price, you need to calculate the discount amount first.
The discount amount is given by multiplying the regular price by the discount rate. In this case, the discount rate is 10% or 0.10.
Discount amount = Regular price * Discount rate
Discount amount = $3.20 * 0.10
Discount amount = $0.32
The sale price is then found by subtracting the discount amount from the regular price.
Sale price = Regular price - Discount amount
Sale price = $3.20 - $0.32
Sale price = $2.88
So, the sale price of the hamburger is $2.88.
