Nate is feeding his livestock hay. Each goat needs 5 pounds, and each sheep needs 3 pounds less than twice the amount each goat needs. If there are 15 goats and 12 sheep, how many pounds of hay does Nate need?

How much hay does each sheep need? ** First figure out how much hay each sheep needs: 5 pounds * 2 - 3 = <<5*2-3=7>>7 pounds/sheep
How much hay does the sheep need? ** Now figure out how much hay total the sheep need: 7 pounds/sheep * 12 sheep = <<7*12=84>>84 pounds
How much hay does the goats need? ** Now figure out how much hay total the goats need: 5 pounds/goat * 15 goats = <<5*15=75>>75 pounds
How many pounds of hay does Nate need? ** Now add the two amounts of hay to find the total: 84 pounds + 75 pounds = <<84+75=159>>159 pounds
