Question

1. Mina bought a plane ticket to New York City and used a coupon for 10% off the ticket price. The

total cost of her ticket, with the discount, was $253.10. Which equation could she use to find the

price of the ticket without the discount?

Answer 1

`x-0.10x=253.10`

Explanation:

Let x represent the price of the ticket without the discount.

The cost of the ticket after discount would be x minus 10% of x.

10% of x:
`(10)/(100)*x=0.10x`

We have been given that the total cost of ticket with 10% discount is $253.10. We can represent the given information in an equation as:

`x-0.10x=253.10`

Therefore, Mina could use the equation
`x-0.10x=253.10` to find the price of ticket without the discount.
