If ms mary has 1 8/9 quarts .she drinks 1 3/9 quarts over the course of a week. how much orange juice

5/9

Step-by-step explanation:

1 8/9 -1 3/9

which will give you 5/9 as your answer

because they could drop even lower..

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
