Gilberto is buying salad and pizza for a company lunch. Suppose that a bowl of salad costs $5.00, and a slice of pizza costs $2.00. Let E be the amount in dollars that Gilberto spends on salad and pizza. If Gilberto buys S bowls of salad and P slices of pizza, then the total amount of money he spends (E) can be represented by the equation . Now rearrange the equation you wrote above so that P is written in terms of E and S. The quantity of pizza he buys can be represented by the equation . Suppose Gilberto has $40.00 to spend on salad and pizza; that is, E = $40.00

Complete the following table with values of S or P that make the equation true.

To complete the first row, determine the number of pizza slices Paolo can purchase with $40.00, when the number of salad bowls he purchases is 0.

Budget (Dollars) Salad (Bowls) Pizza (Slice)
40.00 0
40.00 4
40.00 0
