In a recent 10 year period , the change in the number of visitors to an amusement park was about 15,000 visitors. what was the mean yearly change in the number of visitors ?

3x + 4y -25 =0 represents the amount of change sianna should recieve

b is the correct answer

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
