Answer:

B=3

Step-by-step explanation:

Use a graphing calculator and type in these toe equations

y=2x+13

y=3x+10

and the point they intersect will say (3,19) and the answer is 3

For 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

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.

Let's suppose, for x rounds of bingo, the costs will be the same for an adult and a child.

For x rounds, cost for adult:

= 2x + 13

For x rounds, cost for child:

= 3x + 10

2x + 13 = 3x + 10

x = 3

Thus, for 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.
