I NEED HELP FAST!! The graph shows the prices, in dollars, of different numbers of sandwiches at Juan's store. The table shows the prices, in dollars, of different numbers of scones at the same store.

A graph shows Number of Sandwiches on x-axis and Price of Sandwiches on y-axis. The x-axis scale is shown from 0 to 36 at increments of 6, and the y-axis scale is shown from 0 to 240 at increments of 30. A straight line joins the ordered pairs 6, 30 and 12, 60 and 18, 90 and 24, 120 and 30, 150 and 36, 180.
