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
