Solve the problem.In 1985, in the town of Appleby, 21.2% of Hispanics were overweight, increasing by an average of 0.42% per year. In 1985, in the town of Appleby, 0.17% of whites were overweight, increasing by an average of 31.0% per year. Write a function that models the percentage, y, of Hispanics who are overweight x years after 1985. Write a function that models the percentage, y, of whites who are overweight x years after 1985.
A. Hispanics: y = 0.42x + 21.2 Whites: y = 31.0x + 0.17 B. Hispanics: y = 21.62x Whites: y = 31.17x C. Hispanics: y = 21.2x + 0.42 Whites: y = 0.17x + 31.0 D. Hispanics: y + 0.42x = 21.2 Whites: y + 31.0x = 0.17
