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.



answer: victoria's daughter's cookie recipe uses less flour

step-by-step explanation:

you could set up a proportion (even though they are not equal) to find that the number of grams of butter used by victoria's daughter is twice as much, but the amount of grams of flour used are not (multiplied by 1.6 instead of 2)

problem

you deposit some money into a bank account paying 4% simple interest per year. you received $72 in interest after 3 years. how much the deposit (principal) was?

result

the principal was $600.

explanation

find principal by using the formula i=p⋅i⋅t, where i is interest, p is total principal, i is rate of interest per year, and t is total time in years.

in this example i = $72, i = 4% and t = 3 years, so..
