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
