67. One eight-ounce glass of apple juice and one eight-ounce glass of orange juice contain a total of 227 milligrams of vitamin C. Two eight-ounce glasses of apple juice and three eight-ounce glasses of orange juice contain a total of 578 milligrams of vitamin C. How much vitamin C is in an eight-ounce glass of each type of juice?

There are 103 mg of vitamin C in one eigth-ounce of the apple juice and 124 mg of vitaminc C in one egith once of orange juice

Explanation:

This problem can be solved using equations. So, "x" will be the ounces of apple juice and "y" will be the ounces of orange juice.

In the first equation: (1/8) * x + (1/8) y = 227 mg of vitamin C

In the second, (2/8) * x + (1/8) * y = 578 mf og vitamin C

You need to solve for x in the first equation: x = - y + 1816

And now subtitute that in the second equation, y = 992

Now, you subtitute y in the first equation, x = 824

Now you divide x and y by eigth
