Know the Answer?

Andres Wilcox · Answer 1

150-110 = 40

rate of change would be - 40, the amount withdrawn every month

Arianna Simmons · Answer 2

Ok so if she has 150 and takes out the same amount each month (x) which would be 110 ... so 150-110 would result in 40 however since its every month of being withdrawn then it would result in - 40 A
