Answer:

(b) 2.50P +1.25S = 696.25 and P +S = 384

Explanation:

You want the equations necessary to find numbers of pizza slices and sodas when a total of 384 $2.50 pizza slices and $1.25 sodas were sold for $696.25.

Equations

There are two relations given in the description of the scenario. One relates the numbers of slices and sodas to their total. The other relates the prices of slices and sodas to the total revenue. The required equations describe these relations:

2.50P + 1.25S = 696.25 . . . . . . . equation for revenue

P + S = 384 . . . . . . . . . . . . . . . . . . equation for numbers sold

These equations match choice B.

__

Additional comment

Their solution is P = 173, S = 211. It works well to solve by substitution: S = 384 -P.
