Unit Cost: the price for ONE item

Dollars PER Item

MONEY ALWAYS GOES ON TOP

An 8-pack of Gatorade costs $8.96. How much does ONE bottle cost?

 $\frac{8.96}{8}\ =\ 8.96\ \div8$  

So the unit cost is $1.12 per bottle.

Multiple Choice

6 pounds of Fancy French Fig cookies costs $12.84. What is the price per pound?

• $0.47

• $2.14

• $4.67

• $0.22

Unit cost is important when you are wanting to buy the better deal.

I can buy an 8 pack of batteries for $36 or a 5 pack of batteries for $21.25. Which is the better deal?

 $\frac{36}{8}\ or\ \frac{21.25}{5}$  

 $\frac{36}{8}=\ \text{4.50}$  
 $\frac{21.25}{5}=\ 4.25$  

$4.25 is the better deal so the 5 pack is the better buy!

Multiple Choice

Which is the better buy?

• 15 pounds of apples for $37.50

• 12 pounds of apples for $21.00

 $\frac{21}{12}\ =\ 1.75$  

 $\frac{37.50}{15}=2.50$  

The 12 pack of apples is the better buy.

Multiple Choice

Which is the better buy?

• 24 pences for $25.20

• 28 pencils for $27.72

 $\frac{25.20}{24}=\ 1.05$  

 $\frac{27.72}{28}=0.99$  

28 pack of pencils is the better buy.

REMEMBER:

1. MONEY ALWAYS GOES ON TOP!
2. The better buy is ALWAYS the lowest unit cost!
