Question

Adam goes to a skating rink on Tuesdays for $8.50. While there, he pays $1.50 for each item he buys at the concession stand. Which equation best represents this information?

Answer 1

y = 1.50x + 8.50

Answer 2

Let y = cost
Let x = number of items he buys

y = fixed cost + cost of items he buys

Fixed cost = 1.50

Cost of items:
1 item costs $1.50 * 1
2 items cost $1.50 * 2
3 items cost $1.50 * 3
x items cost $1.50 * x = 1.50x

y = fixed cost + cost of items he buys
y = 8.50 + 1.50x
