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?

i need help with this problem if u know the answer coment the answer below
To calculate the farmer's estimate of yield in bushels/acre, we can follow these steps:
1. Calculate the total number of ears per acre:
Since the farmer counts 22 ears in 1/1000 of an acre, we can use this information to find the number of ears per acre.
Number of ears per acre = (22 ears / 1/1000 acre) * 1 acre
Number of ears per acre = 22,000 ears
2. Calculate the total number of kernels per acre:
Since each ear has about 700 kernels on average, we can multiply the number of ears per acre by the average number of kernels per ear.
Total number of kernels per acre = Number of ears per acre * Average number of kernels per ear
Total number of kernels per acre = 22,000 ears * 700 kernels/ear
Total number of kernels per acre = 15,400,000 kernels
3. Convert the total number of kernels per acre to bushels:
Since a bushel contains about 90,000 kernels on average, we can divide the total number of kernels per acre by the average number of kernels per bushel.
Total number of bushels per acre = Total number of kernels per acre / Average number of kernels per bushel
Total number of bushels per acre = 15,400,000 kernels / 90,000 kernels/bushel
Total number of bushels per acre ≈ 171.11 bushels/acre
Therefore, the farmer's estimate of yield in bushels/acre is approximately 171.11 bushels/acre.
