Dom wants to buy a new backpack. Elliot recommended a store in Williamsburg where
there is a 10% discount on a backpack that costs $45. A sales tax of 4% was applied after
the discount. What was the final price of Dom's Backpack?
Step-by-step explanation: i used an  calculator which of the option of using the percent sign in an equation. i did 45 - 10% of 45 then that got me 40.5 so afterwards i did 40.5 - 4% of 40.5.
