6. A farmer planted a field of Bt 123 corn and wants to estimate the yield in terms of bushels per acre. He counts 22 ears in 1/1000 of an acre. He determines that each ear has about 700 kernels on average. He also knows that a bushel contains about 90 000 kernels on average. What is the farmer's estimate of yield in bushels/acre?

There will be 22,000 ears per acre. Multiply that by 700 for the number of kernels per acre. Then divide by 90,000 kernels per bushel.
The answer will be the number of bushels per acre.

22 ears * 700 kernels = 15400 kernels inn 1/1000 acre = 15,400,000 kernels in an acre = 170 bushels/acre
