Bob 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 Bob spends on salad and pizza. If Bob buys S bowls of salad and P slices of pizza, then the total amount of money he spends (E) can be represented by the equationE=($2.00S)+($5.00P) .
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 Bob has $40.00 to spend on salad and pizza; that is, E=$40.00.
