Answer:
$0.50
50 cents per ounce.
Explanation:
To get the unit price, you take the cost of the package divided by the parts it has. Since Marissa has a package of yogurt that costs $3.50 and there are seven ounces in the package we have this equation:
($3.50)/(7 ounces)= $0.50 = 50 cents = the second answer available.
