Problem
A deli sells meat and cheese by the pound. The expression $7.99 m+5.99 \mathrm{c}$ represents the total cost of $m$ pounds of meat and $c$ pounds of cheese. Which statement is true? Each pound of cheese costs $\$ 5.99$. Each pound of meat costs $\$ 5.99$. The total cost for $c$ pounds of cheese is $\$ 7.99$. The total cost for $m$ pounds of meat is $\$ 7.99$.
Solution
Step 1 ：Let's denote the number of pounds of cheese as \(c\) and the number of pounds of meat as \(m\).
Step 2 ：The cost of cheese per pound is $5.99, so the total cost for \(c\) pounds of cheese is \(5.99c\).
Step 3 ：The cost of meat per pound is $7.99, so the total cost for \(m\) pounds of meat is \(7.99m\).
Step 4 ：Therefore, the statement 'Each pound of cheese costs $5.99' is true.
