Answer:
McCoy should plant soybeans
Step-by-step explanation:
Thinking process:
Let the two crops be corn and soybeans as indicated.
The profit margin for corn will be $ 30 000. However, the loss will be:
$ 35 000 - $ 30 000 = $ 5 000
For the soybean, the profit margin will be $ 10 000.
The loss will be $ 5 000
The net balance will be given as: $ 5 000 - $ 10 000 = - $ 5 000. (This represents a gain)
Thus, soybean will be more profitable.

Answer:
He burnt 1000 calories per hour when playing basketball.
Step-by-step explanation:
Let B be calories burned playing basketball, and C calories burned canoing.
1800 = B + 2C
3200 = 2B + 3C
From 1st equatipn, we get that B = 1800 - 2C
Replacing into the 2nd equation, we have:
3200 = 2(1800-2C) + 3C
3200 = 3600 - 4C + 3C
3200 = 3600 - 1C
C = 3600 - 3200
C = 400
Knowing C, we find B.
B = 1800 - 2C = 1800 - 2*400 = 1800 - 800 = 1000 calories.
