Kindly, tell me how this question will be solved, please.

Thank you.

a) From the early 1970’s through 2001, the rate of obesity in young American children, ages 6 to 11, has shown a linear increase. In 1988, approximately 10.23 % of 6-11 year old American children were obese. By 2001, the rate of obese American had risen to 15 %. Write a linear model that would model these data where t = time in year after 1988 and R is the Rate of obesity as a percentage. Round your answer to two decimal places if necessary.
Solution:
b) Use this model to predict the 2016 obesity rate among 6-11 year old American chil
