30) To help sell more of a lower grade meat, a butcher mixes some premium ground beef worth $3.10/lb,
with 8 lb of lower grade ground beef worth $2.05/lb. If the result was an intermediate grade of ground
beef worth $2.68/lb, how much premium ground beef was used?
a) Use a table to clearly organize the information. Be sure to correctly label each row and column. If
necessary, use variable names that make sense in the context of the problem (do not use x or y).
b) Use your answer to part a to set up a linear equation in one variable that can be solved to determine
the amount of premium ground beef that was used.
c) Rewrite and solve your equation from part b. Work vertically, keep = signs lined up. Round to the
nearest hundredth of a pound, if necessary.
