Answer:
10 milligrams of Medication A
Step-by-step explanation:
We'll write proportions/ratios for this:
20:16 is the usual proportion, and x:8 is this week's dose. The ratio from A to B has to be equal, so
20/16 = x/8
Cross-multiply:
(20)(8) = (16)(x)
160 = 16x
divide both sides by 16
x = 10

Hi Candisjhnsn,
To get the answer we need to add, subtract, and divide. So, for the first month we pay $115 cause $65 + $50 = $115. So, $850 - $115 = $735. Now, $735/$65 = 11.3076923077 but, you can't have .3076923077 of a class so, she will only have enough for 11 classes.
Hope This Helps!
