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 child. For how many rounds of bingo are the costs the same for an adult and a child?.

Answer :

An equation is formed of two equal expressions. The number of rounds of bingo for which the cost of a child and an adult will be equal is 3.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of rounds played be represented by x.

Given the rounds of bingo costs the same for an adult and a child for x number of games, therefore,

13 + 2x = 10 + 3x

13 - 10 = 3x - 2x

3 = x

Hence, the number of rounds of bingo for which the cost of a child and an adult will be equal is 3.
