My question is: A gallon of whole milk that normally costs $3 is now sold at $2. A box of cereal was sold at a discount of $1. How much will you save via discounts if you buy 3 gallons of whole milk and 5 boxes of cereal? Your thoughts:
The discount for each gallon of whole milk is $3 - $2 = $1. So the discount for 3 gallons of whole milk is $1 / gallon x 3 gallons = $3. The total discount for 5 boxes of cereal is $1 / box x 5 boxes = $5. You will save $3 + $5 = $8 for 3 gallons of whole milk and 5 boxes of cereal. The final answer: 8.
