Answer:

Equation: $8.5t+6.5=57.5$

Solution: $t=6$

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

$8.5t$

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

$8.5t+6.5$

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

$8.5t+6.5=57.5$

Finally, you can solve for "t" in order to find the solution of the equation. This is:

$8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6$
