Sarah bought a 20oz can of tomato sauce for $25.40.What is the unit Price per ounce
ddd [48]
If the can is 20oz and cost $25.40, the price per ounce would be:

\frac{price}{ounce}

price = $25.40
ounce = 20oz

so:

\frac{25.40}{20}

which comes out to be:

$1.27/oz

So each ounce of tomato sauce costs $1.27!
