To maintain a healthy diet, no more than 30% of calories consumed each day should come from fat. a normal teenage girl needs about 2,000 calories each day how many calories should come from sources other than fat in a teenage girls diet each day?

1400 becaude 30% of 2000 is 600 and then you subtract that from 2000 to find 70% which is 1400

f(x) has value 150 at x= 0

and 0 at x= 3

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