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.
