Answer:

Explanations:
Given the following parameters:
• Cost of a bowl of salad = $5.00
,
• Cost of a bowl of pizza = $2.00
If Nick buys S bowls of salad, the total money spent on salad will be $5S
If Nick buys P bowls of pizza, then the total money spent on pizza will be $2P
Since E represents the amount in dollars that Nick spends on salad and pizza, the total amount (E) he spends is given according to the equation:

Next is to write P in terms of E and S.
Given the equation:

Subtract 5S from both sides of the equation

Divide both sides by 2:

Therefore the quantity of pizza (P) he buys can be represented by the equation
P = (E-5S)/2
