What is the unit rate for 12 cans for $3.99

Question

I can't remeber how to do unit rates

Answer 1

• The question is looking for the cost per can, so you need to divide.
• If it costs $3.99 to buy 12 cans, how much will it cost to buy 1 can?
• You figure this out by dividing $3.99 by 12 (or $3.99/12) and getting $0.3325
• Since our answer is represented in cents, we only want two decimal places, so our final answer is $0.33.

Answer 2

You divide the total price by the number of units.

 

So the answer is $3.99 / 12 = $0.3325 per can = 33.25 ¢ per can.
