One eight-ounce glass of apple juice and one eight-ounce glass of orange juice contain a total of 183.0 milligrams of vitamin C. Two eight-ounce glasses of apple juice and three eight-ounce glasses of orange juice contain a total of 453.1 milligrams of vitamin C. How much vitamin C is in an eight-ounce glass of each type of juice?

r = 87.1ml

a = 95.9ml

Step-by-step explanation:

Let apple = a and orange = r

Using the equations:

a + r = 183 (1)

2a+3r = 453.1 (2)

Multiply the 1st equation by 2 to get:

2a + 2r = 2 × 183

2a + 3r = 453.1

Subtract the 1st from the 2nd and solve for "r":

r = 453.1 - 366

r = 87.1 ml of vitamin C

The is amounr of vitamin C in one orange = 87.1ml

Since a + r = 183, 

a + 87.1 = 183

a = 95.9 ml of vitamin C

The amount of vitamin C in one apple = 95.9ml
