Example BFeline delight costs 3.00 for an
eight-ounce can. If you feed two cans per day,
how much will you spend in one year?

• You feed two cans a day.
• There are 365 days in a year.
• So
• Two cans per day X 365 days in a year 730
  cans

Example C Puddy Tat Vitamin Supplements cost
15.00 for a 16 oz bottle. If you give your cat
1/4 ounce per day, how many days will that bottle
last?

• There are 16 ounces in the bottle
• You feed 1/4 ounce per day

Example D You buy a 25 Ib. bag of dog food at
the feed store for 7.00. Your dog will eat two
eight oz servings per day. How much is it
costing you per day to feed the dog?
9
Example D You buy a 25 Ib. bag of dog food at
the feed store for 7.00. Your dog will eat two
eight oz servings per day. How much is it
costing you per day to feed the dog?

• The dog eats two eight ounce servings per day.
• Two X eight ounce servings 16 ounces per
  day or 1 pound
• To calculate cost per pound of the food use this
  formula Cost pounds
• 7.00 25 pounds .28 per pound
• So
• Take the pounds the dog eats per day times the
  cost per pound
• 1 pound per day X .28 per pound .28
  per day

Example E You buy a five-pound bag of dog food
for 3.00. Your dog eats two eight-ounce servings
per day.How many bags must you buy in one
year?What is the annual cost?
11
Example E You buy a five-pound bag of dog food
for 3.00. Your dog eats two eight-ounce servings
per day.How many bags must you buy in one
year?

• The dog eats two eight ounce servings per day.
• Two X eight ounce servings 16 ounces per
  day or 1 pound
• To calculate the days a bag will last, divide the
  weight of the bag by the pounds per day the dog
  eats.
• 5 pound bag 1 pound per day 5 days per bag
• To calculate the number of bags per year, divide
  the days in a year by the days per bag.
• 365 days in a year 5 days per bag 73 bags
  per year.

12
Example E What is the annual cost?

• 73 bags per year X 3.00 per bag 219.00
