Seed corn was $5 and dog food was $3 a bag.
Joe bought 50 bags and spent $190.
How many bags of dog food did he buy

Answer 1

30 bags of dog food and 20 bags of corn.

Answer 2

Joe bought 20 seed corn bags and 30 bags of dog food

Explanation:

x + y = 50

5x + 3y = 190

Subtract y from both sides of the first equation

x = 50 - y

Put x into the second equation

5(50 - y) + 3y = 190

Distribute the 5

250 - 5y + 3y = 190

Combine like terms

250 - 2y = 190

Subtract 250 from both sides

-2y = -60

Divide both sides by -2

y = 30

Put y into the first equation

x + 30 = 50

Subtract 30 from both sides

x = 20
