Ms.sanders is buying three 112-oz bottles of laundry detergent for her family. Each bottle has the same price. The total cost of the detergent , including $1.60 in sales tax, is $41.65 . To the nearest cent what price per ounce of the detergent before tax?

Respuesta :

It would be 11 cents
Let x represent the price of laundry detergent
3x+1.6=41.65
3x=40.05
x=$13.35 divided 112=$0.12. As a result, the detergent costs $0.12 per ounce. Hope it help!
