How to find rate?
In mathematics, a rate is the ratio between two related quantities in different units.
Chrissy compared ice cream scoop prices at a local ice cream parlour.
- 2 scoops for $2.98
- 3 scoops for $3.69
- 4 scoops for $4.28
The number of scoops that have the best rate can be calculated as follows:
- 2 scoops for $2.98
rate = 2.98 / 2
rate = 1.49 dollars per scoop
- 3 scoops for $3.69
rate = 3.69 / 3
rate = 1.23 dollars per scoop
- 4 scoops for $4.28
rate = 4.28 / 4
rate = 1.07 dollars per scoop
Therefore, 4 scoops for $4.28 is the best rate.
