A company orders boxed lunches from a deli, which all cost the same price. The relationship between the number of boxed lunches ordered, xx, and the total cost in dollars of the lunches, yy, is represented by a graph drawn in the xy-plane.

Question

If the point (3, comma, 243,24) lies on the graph, what does the ordered pair (3, comma, 243,24) indicate?

Answer 1

The ordered pair (3, 243.24) indicates that when the company orders 3 boxed lunches from the deli, the total cost for these lunches is $243.24. In other words, if x represents the number of lunches ordered and y represents the total cost, this particular point tells us that ordering x = 3 lunches corresponds to a cost of y = $243.24. This also implies that each boxed lunch costs $81.08 since 243.24 ÷ 3 = 81.08.
