Katrina is fostering a kitten and needs to purchase cat litter. Clean Cats costs $10 for a 25-pound bag, and Forever Fresh costs $18 for a 40-pound bag. What is the cost per pound of the better cat food?

Answer 1

To find the cost per pound for each brand of cat litter, we need to divide the total cost by the total weight for each.

1. Clean Cats:

   • Cost: $10
   • Weight: 25 pounds
   • Cost per pound = Total cost / Total weight \[ \text{Cost per pound for Clean Cats} = \frac{10}{25} = 0.40 \text{ dollars per pound} \]

2. Forever Fresh:

   • Cost: $18
   • Weight: 40 pounds
   • Cost per pound = Total cost / Total weight \[ \text{Cost per pound for Forever Fresh} = \frac{18}{40} = 0.45 \text{ dollars per pound} \]

Now we can compare the two costs per pound:

• Clean Cats: $0.40 per pound
• Forever Fresh: $0.45 per pound

Thus, Clean Cats is the better option at $0.40 per pound.
