Proportionality in Graphs

A deli charges the same price, $5.20, for all of its different sandwiches. If a company ordered n sandwiches for a luncheon, which equation could be used to find the total price, P, that the deli charged for the sandwiches?

• n/$5.20 = P
• $5.20/n = P
• $5.20n = P
• $5.20 + n = P
