Namid works for a florist and is making flower arrangements for the tables at a reception. he has 36 roses, 48 tulips, and 72 carnations. each case must contain the same number of each type of flower. how many cases will namid need? how many of each type of flower will he put in one case?

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

c. product line extension.
