Answer:

1. If Eric spends e on salad and pizza and salad costs $5.00 and is represented by s and pizza costs $3.00 is represented by p then the total amount that Eric spends an be represented by the equation;

e = 5.00s + 3.00p

Where the total amount is the cost of the number of bowls of salads taken and the number of pizza slices bought.

2. Rewritting the equation so p is written in terms of e and s;

e = 5.00s + 3.00p

3.00p = e - 5.00s

[tex]p = \frac{e - 5.00s}{3.00}[/tex]

3. Suppose Eric has $30.00 to spend on salad and pizza; that is, e=$30.00, how much pizza can he buy if he buys 3 bowls of salad.

[tex]p = \frac{e - 5.00s}{3.00}[/tex]

p = (30 - 5.00 * 3) / 3.00

p = 5 slices of pizza
