I need help with a finite math problem. I'm in chapter 2 lesson 6 of finite math, and I'm stuck on question 41. Which asks:

Jackson Farms has allotted a certain amount of land for cultivating soybeans, corn, and wheat. Cultivating 1 acre of soybeans requires 2 labor-hours, and cultivating 1 acre of corn or wheat requires 6 labor-hours. The cost of seeds for 1 acre of soybeans is $12, for 1 acre of corn is $20, and for 1 acre of wheat is $8. If all resources are to be used, how many acres of each crop should be cultivated if the following hold?

a.) 1000 acres of land are allotted, 4400 labor-hours are available, and $13,200 is available for seeds.

b.) 1200 acres of land are allotted, 5200 labor-hours are available, and $16,400 is available for seeds.
