Question

A 2-gallon jug of juice costs $8.40 what is price per quart

Answer 1

We are told that 2 gallons cost $8.40. To determine how much a quarter of a gallon costs we need first find the price per gallon. To do that we divide the cost over the number of gallons, like this:

`N=\frac{8.40\text{ dollars}}{2\text{ gallon}}=4.20\text{ dollars/gallon}`

Now we multiply the price by 1/4 gallons:

`(4.20\text{ dollar/gallon)(1/4 gallon)=}1.05\text{ dollars}`

therefore, a quarter gallon costs $1.05
