Monica and Lauren plan to buy some of their dry ingredients (particularly flour, sugar, and baking soda) in prepackaged containers. Each container with the three dry ingredients weighs
22 pounds. The weight of the sugar in each container is 2 times the amount of baking soda.
Also, there are 14 pounds more flour than baking soda in each container.
The girls want to calculate the weight of baking soda in each container, but they claim that the
necessary equation is impossible because it has infinitely many solutions.
Identify an equation that proves the girls' claim is wrong and explain why that equation does not
have infinitely many solutions.
