Activity

This activity is an extension of the expectations in the TEKS.

For questions 1 – 6, use the following scenario:

A popular band is trying to raise at least $20,000 for charity by holding multiple concerts at a park. It plans to sell tickets at $25 each. For each 2-hour concert, the band would need to pay the park $1,250 in fees for security, cleaning, and traffic services.
The band needs to find the combinations of number of tickets sold, tt, and number of concerts held, cc, that would allow it to reach its fundraising goal.
