Final answer:
To find the cost of various meats per pound, use the expression Cost = (price of chicken per pound x c) + (price of beef per pound x b) + (price of salami per pound x s). Applying this to specific quantities, the cost for 1 pound of chicken, 1.8 pounds of beef, and 3.2 pounds of salami comes to $19.38.
Step-by-step explanation:
To calculate the cost of buying c pounds of chicken, b pounds of beef, and s pounds of salami, you can represent the total cost by the expression:
Cost = (3.80 × c) + (3.50 × b) + (2.90 × s)
Substituting the given values into the expression to find the cost for 1 pound of chicken, 1.8 pounds of beef, and 3.2 pounds of salami:
Cost = (3.80 × 1) + (3.50 × 1.8) + (2.90 × 3.2)
Cost = 3.80 + 6.30 + 9.28
Cost = $19.38
Therefore, the total cost for the meats is $19.38.
