A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a ch
anygoal [31]

For this case we have to:

x: Be the variable that represents the number of adult rounds

y: Be the variable that represents the number of rounds of children

We want to know for what amount of rounds bingo costs are the same for adults and children.

Adult costs = 2x + 13

Child costs = 3y + 10

Matching:

2x + 13 = 3y + 10

We want the same number of rounds, x = y:

2x + 13 = 3x + 10\\2x-3x = 10-13\\-x = -3\\x = 3

Thus, for 3 rounds the costs are the same.
