Question

A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. The total includes the cost of each sub, plus the delivery fee.

Answer 1

cost of each sub = $6, delivery fee = $2

Explanation:

Let $x be the cost of each sub and $c be the delivery fee

3x + c = 20

4x + c = 26

x = 6, c = 2
