Answer:
$1.30
Step-by-step explanation:
As with costs anywhere, you find the total cost by multiplying the unit cost by the number of units. Here, a unit is 1 ounce of tomato sauce. 3.5 units are used in the recipe. The unit cost is given as $0.37 per ounce.
__
cost of sauce = (cost per ounce) × (number of ounces)
= ($0.37) × 3.5 = $1.295
This rounds up to $1.30.
The sauce for one portion costs $1.30.
