Dave is buying pizza and soda. suppose that a slice of pizza andd a can of soda cost $3. let e be the amount in dollars that dave spends on pizza and soda. if dave buys p slices of pizza and s cans of soda, which equation correctly describes the amount of money he spends? e=p+3s e=3p+s e=p+s e=3p+3s 3e=p+s 2. now rearrange the equation you wrote above so that s is written in terms of e and p. which of the following is correct? s=p+e s=(1/3)e-p s=e-3p s=3e-3p s=e-p

E = 3P + 3S,

S=(1/3)E-P

Step-by-step explanation:

Given,

A slice of pizza and a can of soda cost $3,

That is, total cost of P slices of pizza and S cans of soda = ( 3P + 3S ) dollars,

According to the question,

Total cost of P slices of pizza and S cans of soda = E dollars,

⇒ 3P + 3S = E

Which is the required equation that correctly describes the amount of money spent,

For rearranging the equation in terms of E and P,

We need to isolate S,

Subtract 3P on both sides,

3S = E - 3P

Divide both sides by 3,

Which is the required equation.
