Final answer:

To model the situation, the equation x + ((x/2) + 20) = 80 can be used. Solving for x yields the solution x = 40, so Ted sold 40 tickets and Bill sold 60 tickets.

Step-by-step explanation:

To write an equation to model the situation, we need to let x represent the number of tickets Ted sold. Bill sold 20 more than half the amount of Ted, so we can express the number of tickets Bill sold as (x/2) + 20. The total number of tickets sold is 80, so our equation becomes:

x + ((x/2) + 20) = 80

To solve for x, we can simplify the equation:

2x + x + 40 = 160

Combining like terms:

3x + 40 = 160

Subtracting 40 from both sides:

3x = 120

Dividing both sides by 3:

x = 40

Therefore, Ted sold 40 tickets and Bill sold (40/2) + 20 = 40 + 20 = 60 tickets.
