2) Unit rate or cost – when one of
the numbers equals 1
Ex. 2:1

2. Ex 1: Find the unit rate or unit price.
A)
hours4
miles100
B)
cans4
402.$
25
1004= = 25 mi/hour
60.0
40.24= = $.60/can

3. Find the total amount using
the unit rate.
$5.25 per hour for 7 hours
$6.32 per hour for 5 hours
5.25 x 7 = $36.75
6.32 x 5 = $31.60

4. Ex 2: Find the unit rate, then solve.
A) A 2 lb. package of candy costs $3.98;
a 3 lb. package costs $5.67. Which is a
better buy?
99.1
98.32
89.1
67.53
$1.89/lb. is cheaper
than $1.99/lb., so
the 3 lb. package is a
better buy.
