Answer:
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_________ .
E = 5S + 2P
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___________ .
P = 0.5E - 2.5S
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.
E S P
$40 0 20
$40 4 10
$40 8 0
P = 20 - (2.5 x 0) = 20
P = 20 - (2.5 x 4) = 10
P = 20 - (2.5 x 8) = 0
