The tax rate on a gallon of gas is 20 c per gallon. If a gallon of gas costs $2.12, what is the amount of the tax paid on a purchase of 10 gallons rounded to the nearest cent?

Respuesta :

$23.2

First Multiply 2.12 by ten to get 21.2, and then we multiply 0.20 by ten to get 2 and then we add both to get 23.2
