Question

What is the unit rate of a quart (32 ounce) bottle of milk cost 1.19?

Answer 1

1.19 dollars/quart x 1 quart/ 32 ounces = .037 = 3.7 cents per ounce

when you set up the multiplication, since quarts are in the denominator initially and you want to get rid of them, set the quarts in the numerator of the unit rate (1 quart/ 32 ounces) so that the units cancel and you are left with the units that you wanted ($/ounce).

Clear as mud?! :)

Answer 2

The unit rate is
`\$0.037`

Explanation:

Givens:

• 1 quart equals 32 ounces.
• A quart bottle of milk costs $1.19

The unit rate refers to the cost per ounce. Here we can use the rule of three, if 1 quart is 32 ounces and it costs $1.19, how much would be 1 ounce:

`1oz(\$1.19)/(32oz)=\$0.037`

Therefore, the unit rate is
`\$0.037`
