Solve the problem.The following bar graph shows the average annual income for single mothers.
i) Determine a linear function that can be used to estimate the average yearly income for single mothers from 1995 through 2000. Let t represent the number of years from 1995. (In other words, 1995 corresponds to t = 0, 1996 corresponds to t = 1, and so on.)ii) Using the function from part i, determine the average yearly income for single mothers in 1998.iii) Assuming this trend continues, determine the average yearly income for single mothers in 2010.iv) Assuming this trend continues, in which year will the average yearly income for single mothers reach
