Question

"Tiffany has been dieting for 6 months. After 1 month Tiffany lost a total of 8 pounds. After 6 months, she lost a total of 25 pounds. Find the average rate of change of pounds per month."

I got 3.4. Is this correct?

I used the slope formula, so
m=(25-8)/(6-1)
m=17/5
m=3.4

Answer 1

\(\dfrac{25-8}{6-1} = \dfrac{17}{5} = 3.4\)

you are correct
