# The cost of a plane ticket was increased by $15. The new price is $84. What was the price before the increase?

The price before the increase is $69.

Use the equation: x + 15 = 84 x = the price before the increase 15 = how much the ticket has increased 84 = the resulting price of the increase

Simply subtract 15 from both sides of the equation. The result is x = 69.

Let ( x ) represent the original price of the plane ticket.

Given that the cost increased by 15, the new price is \( x + 15 \), which is 84.

So, ( x + 15 = 84 ).

To find the original price (( x )), subtract 15 from both sides:

( x = 84 - 15 )

( x = 69 )

Therefore, the price before the increase was $69.
