3 rounds of bingo

Step-by-step explanation:

Let x represent the number of bingo rounds

For adults, the total cost can be represented by 2x + 13, since it is $2 per game and there is a $13 entry fee

For children, the cost can be represented by 3x + 10, since it is $3 per round and there is a $10 entry fee

To find how many rounds are needed to make the cost the same, set these expressions equal to each other and solve for x:

2x + 13 = 3x + 10

13 = x + 10

3 = x

So, costs will be the same with 3 rounds of bingo

explanation:

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
