There are 15 students in Mr. Weiss's chess club. The ratio of the number of boys to the number of girls in the club is 3 : 2. If the number of boys in the club does not change, how many additional girls would need to join the club in order for the ratio of the number of boys to the number of girls in the club to be 1:1​

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

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
