Jackie needs to buy chicken feed for her chickens. She can buy a 40 pound bag for $30.99 or a 10 pound bag for $12.98. Which size bag is cheaper per pound?

Answer 1

To determine which bag of chicken feed is cheaper per pound, we need to calculate the cost per pound for each size.

1. 40-pound bag:

   • Cost: $30.99
   • Price per pound: \( \frac{30.99}{40} \)

   \[ \frac{30.99}{40} = 0.77475 \text{ (approximately 77.48 cents per pound)} \]

2. 10-pound bag:

   • Cost: $12.98
   • Price per pound: \( \frac{12.98}{10} \)

   \[ \frac{12.98}{10} = 1.298 \text{ (approximately 129.80 cents per pound)} \]

Now we can compare the two prices:

• 40-pound bag: $0.77475 per pound (approximately 77.48 cents)
• 10-pound bag: $1.298 per pound (approximately 129.80 cents)

Thus, the 40-pound bag is cheaper per pound.
