Bloomin' GeniusPlayback speed:
At the store, a 12-ounce box of cereal costs $3.60. An 18-ounce box of the same cereal costs $4.50. Which box is the better buy?
In this video
- Find the unit price: the price of 1.
- Compare another way by making the amounts match.
- Use the same idea for constant speed.
Try it together
A 6-pack of juice costs $4.20. A 10-pack costs $6.50. Which is the better buy?
Show the answer
The 10-pack
$4.20 ÷ 6 = 70¢ per juice. $6.50 ÷ 10 = 65¢ per juice. The 10-pack costs less for each one.
Ask, don't tell
“What does 25¢ per ounce mean?”
“How many miles does the car go in 1 hour? In 2 hours?”
