3. When a boy was 4 years old, he weighed 16 kg. For the next 7 years, his weight increased by approximately 14% each year. His weight when he was 9 years old was approximately 30.8 kg. a. Assume that this pattern continues. Make a table showing the age of the boy for ages 4 to 14.

b. What degree of accuracy did you use for the weight of the boy? (for example, to the nearest 10 kg, to 4 decimal places, to 5 significant figures, or to another level of accuracy)?

c. Write an equation for in terms of , where represents the weight of the boy and represents the years since the boy was 4. does not represent the age of the boy.

d. Use your equation to predict the weight of the boy when he is 30 years old. Does the answer make sense? Why or why not?

e. Use a different method to predict the boy’s weight when he is 30 years old. Explain your method.
