Six friends all use $2-off coupons to buy themselves movie tickets. They spend a total of $42.what is the price of me movie ticket without the coupon

Answer 1

Let x be the price of movie ticket. The ticket price after use off coupon is,

`x-2`

The price of six friends ticket is,

`6(x-2)`

The total money spend on tickets is 42. So,

`6(x-2)=42`

Solve the equation for x.

`\begin{gathered} 6(x-2)=42 \\ x-2=(42)/(6) \\ x=7+2 \\ =9 \end{gathered}`

So price of ticket without the coupon is 9.

Answer: 9
