18. A farmer planted a field of BT 123 corn and wants to estimate the yield in terms of bushel per acres. He counts 22 ears in 1/100 of acres. He determines
that each ear has 700 kernels on average. He also knows that a bushel contains about 90,000 kernels on average. What is the farmerâ€™s yield per acres?

22 * 700 = 15,400 kernels per 0.01 acres.
100 * 15,400 = 1,540,000 kernels per acre.
1,540,000 / 90,000 = 17.11 bushels per acre
