Example Question #11 : How To Find Decimal Fractions
A retailer can only order wristbands in bulk cases. Each case has 300 wristbands and costs $1172.
Quantity A: The number of wristbands that can be bought for $10547.
Quantity B: The number of wristbands that can be bought for $10560.
The two quantities are equal.
Quantity A is greater.
Quantity B is greater.
The relationship cannot be determined.
Quantity B is greater.
The key to this problem is to realize that the store cannot buy partial crates of wristbands--it's all or nothing. Calculate how many crates can be bought with each sum of money by dividing the sum by the price of a crate.
Quantity A:
Although oh so close, only eight crates can be bought with this sum of money. Don't round up!
Quantity B:
There's just enough to buy nine crates.
Quantity B is greater.
