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?

If the bushels have kernels:
(22 * 1000 * 700)/ 90000 = ?
I hope this helps.

( 22 ears ) ( 1000 / acre ) ( 700 kernels / ear ) ( 1 bushel / 90,000 kernels ) = 170 bushels / acre
