Problema Solution
An investment is worth $3690 in year 0, the initial investment year. By year 4 its value has increased to $5802. Let y be the value of the investment in the year x. Find and interpret the average rate of change in value per year.
Answer provided by our tutors
we find slope
(0, 3690) and (4, 5802)
slope = rise/run = (5802-3690) / (4 - 0) = 2112/4 = 528
average rate of change = 528
and it means every year the investment is increasing by amount $528
