Question

n 1820, during the Westward Expansion of settlers to territories beyond the Mississippi River, a small farmer in Illinois named John Carter sold livestock, including cows, pigs, and chickens, to travelers passing through the area. Mr. Carter sold 34 animals in a week. He sold 6 more pigs than cows and five times as many chickens as cows. If x is the number of cows, the following equation describes the situation.

x + (x + 6) + 5x = 34

If Mr. Carter sold the cows for $2.50 per cow, how much money, in dollars, did he make by selling cows that week?
