Question

Type 1: Slope and y-intercept

Henry purchased tickets to a park and paid for parking. The tickets cost $25.95 each and the parking cost $12. The total cost was $193.65. Write an equation to represent the total cost.

Answer 1

The equation that represent the total cost is
`25.95x+12=193.65`

The number of tickets was 7

Explanation:

Let

x ----> the number of tickets

we know that

The total cost is equal to multiply the number of tickets by the cost of each ticket plus the parking cost

so

`25.95x+12=193.65`

solve for x

subtract 12 both sides

`25.95x=193.65-12`

`25.95x=181.65`

`25.95x=181.65`

Divide by 25.95 both sides

`x=7\ tickets`
