34. You are buying $80 worth of lawn seed that consists of two types of see. One type is a quick growing rye grass that
that costs $3.80 a pound, and the other type is a higher quality seed that costs $5 a pound.
a. Write an equation in standard form that models the possible combinations of each kind of rye grass you can
buy for $80
b.
How many pounds of quick growing rye seed can you buy if you buy 15 pounds of the higher quality seed?
c. How many pounds of the higher quality seed can you buy if you buy 18 pounds of quick growing rye?
35. You can buy sheets of basic craft paper for $0.10 each and sheets of textured craft paper for $0.13 each. Write an
equation in standard form that models the possible combinations of each kind of paper you can buy. Then list
three possible combinations.
