The number of rounds of bingo when the two costs would be the same is 3.
<h3>When would the two costs be the same?</h3>
The equation that represents the total cost for adults is : 13 +2r
The equation that represents the total cost for children: 10 + 3r
where r is the number of rounds
When the two costs are the same, the two above equations would be equal: 13 + 2r = 10 + 3r
13 - 10 = 3r - 2r
r = 3

Answer:
This is GP with the first term of 512 and common ratio of 1/2
<u>The formula for nth term is:</u>
<u>The number of teams after the 4th round:</u>
- a₄ = 512*(1/2)⁴ = 32 teams
<u>Number of rounds to determine the champion:</u>
- 1 = 512*(1/2)ⁿ
- 2⁰ = 2⁹*2⁻ⁿ
- 0 = 9 - n
- n = 9 rounds
