Question

A cup of rolled oats (x) provided 310 calories. A cup of wheat flakes (y) provided 290 calories. A new breakfast cereal combines wheat and oats to provide 302 calories per cup. How much of each grain does 1 cup of the cereal contain?
a.. Write one equation about the amount of grain
b.Write a second equation about the number of calories.

Answer 1

a)
We use x cups of oats and (1-x) cups of flakes to get one cup of the new combined cereal.

310*x + 290 * (1-x) = 302
Solving this you'll get:
x = 0.6 = 3/5
1-x = 0.4 = 2/5
3/5 of oats and 2/5 of flakes will give you the perfect cereal :)

Answer 2

what are the equations?

Answer 3

310*x + 290 * y = 302
x+y=1
