Answer 2

Answer:

Step-by-step explanation:

Let x represent the amount that Lisa paid for the pizza.

Steven said he could pay twice as much as Lisa. This means that the amount that Stephen would pay would be

2 × x = 2x

Mark said he could pay the remaining $3 which is $1 less than Lisa's share. This means that the amount that Mark could pay would be

3 = x - 1

x = 3 + 1 = 4

amount that Stephen would pay would be

2x = 2 × 4 = 8

Total cost of the pizza is the sum of the amount paid by Stephen, Lisa and Mark. It becomes

4 + 8 + 3 = $15
