The snack bar at a basketball game sold the items below.

• 12 hot dogs for $1.25 each

• 10 water bottles for $1.50 each

• 8 ice cream cones for $1.10 each

The snack bar had to pay $22.25 to rent the space. Which equation below can be used to determine, p, the profit made by the snack bar?

• (12 × $1.25) + (10 × $1.50) + (8 × $1.10) = p
