Answer:
117mg/one eight-ounce glass of apple juice
128mg/one eight-ounce glass of orange juice
Step-by-step explanation:
Let the milligram of Vitamin C in one eight-ounce glass of apple juice=x
Let the milligram of Vitamin C in one eight-ounce glass of orange juice=y
One eight-ounce glass of apple juice and one eight-ounce glass of orange juice contain a total of 245 milligrams of vitamin C.
x+y=245
Two eight-ounce glasses of apple juice and three eight-ounce glasses of orange juice contain a total of 618 milligrams of vitamin C.
2x+3y=618
We solve simultaneously
x+y=245
2x+3y=618
From the first equation, x=245-y
Substitute into the second equation
2(245-y)+3y=618
490-2y+3y=618
y=618-490=128
Recall, x=245-y
x=245-128=117
Therefore, there are 117 milligram of Vitamin C in one eight-ounce glass of apple juice and 128 milligram of Vitamin C in one eight-ounce glass of orange juice.
