Answer:
The maximum number of acres of barley the farmer can plant and still be under budget would be of 123 acres.
Explanation:
The farmer grows two types of seeds, with a budget of $10,000. He has spent $4,200 in wheat seed, and wants to know the maximum number of barley he is able to plant.
First of all, as $10,000 - $4,200 is equal to $5,800, that is the amount of money he is able to spend in barley seeds.
As every acre of barley seed costs $47 to plant, in order to know how many acres he can plant we have to do the following calculation:
5,800 / 47 = maximum of acres the farmer can plant
5,800 / 47 = 123.40
The maximum number of acres of barley the farmer can plant and still be under budget would be of 123 acres.
