The Chemistry Club is experimenting with different mixtures of water with a certain chemical to make fake snow.

To make each mixture, the students start with some amount of water, and then add

1/7 of that amount of the chemical, and then 9 more grams of the chemical. The

chemical is expensive, so there can't be more than a certain number of grams of the

chemical in any one mixture. How much water can you start with so that you don't

use up too much of the chemical?

a. 1/7x + 9 < 26.25

b. 9x + 1/7 s 26.25

26.25x + 9 = 1/7

C.

d. 1/7x + 26.25 39
