Question

Help Please!!! Frank mixed two different cereals to make 10 lb. cereal bags. If brand A costs $2.10/lb. and brand B costs $2.60/lb. how many pounds of each brand should he mix to sell the bags $25.

Answer 1

Let x = amount of brand A cereal (in pounds) and y = amount of brand B cereal (in pounds)


The word problem translates to the two equations

x+y = 10
2.10x + 2.60y = 25*10

Answer 2

use either substitution or elimination to solve for x and y.
