A restaurant buys different types of meat in bulk. The table shows the cost per pound and the density (pounds per cubic foot) for four types of meat:
| Meat type | Density (lb/ft³) | Cost per pound ($) |
|---|---|---|
| Beef | 62 | $4.50 |
| Pork | 58 | $3.20 |
| Chicken | 65 | $2.80 |
| Lamb | 60 | $5.10 |
The equation gives the total cost, in dollars, of the meat purchased, where is the volume of beef in cubic feet and is the volume of pork in cubic feet. If the restaurant purchased all four types of meat, which of the following is the best interpretation of the value in this equation?
The total cost of the chicken and lamb purchased.
The total volume of the chicken and lamb purchased.
The total cost of the beef and pork purchased.
