Ryan is going to make a sculpture from a rectangular block of clay. The volume of the block is (x + 8)(x – 3)(2x – 5). Which statement about the volume of the block of clay is true?

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

your answer is #3 , 8 - 3 square root of 11
