Complete Question:
The container of a breakfast cereal usually lists the number of calories and the amounts of protein, carbohydrate, and fat contained in one serving of the cereal. The amounts for two common cereals are given below. Suppose a mixture of these two cereals is to be prepared that contains exactly 295 calories, 9 g of protein, 48 g of carbohydrate, and 8 g of fat. a. Set up a vector equation for this problem. Include a statement of what the variables in your equation represent. b. Write an equivalent matrix equation, and then determine if the desired mixture of the two cereals can be prepared.

Solution:
Representation of data in equation.
x1 is the number of servings of Cheerios and
x2 is the number of servings of Natural Cereal
110
+ 130
= 295
4
+ 3
= 9
20
+ 18
= 48
2
+ 5
= 8

It depends on if you have your required amount of credits for mathematics. If you do, then you don’t have to take any more mathematics classes, but if you don’t then you’ll still have to take an alternative mathematics class/es in order to graduate. Classes that are dropped will appear on your transcript as so
