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= 1.5x + 8.5

1.50 every time plug in x for how many items and u have to pay 8.50 for just entering

Answer 2

`y = 1.50x+8.50`

Explanation:

Given : 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.

To Find : Which equation best represents this information?

Solution :

Let the total cost be y

let no. of items he buys = x

Since cost of 1 item is $1.50

So, cost of x items is 1.50 x

Since cost of skating is $8.50

So, the total cost =
`1.50x+8.50`

⇒
`y = 1.50x+8.50`
