Answer
Explanation:
Step1: Calculate unit - price of 5 - ounce tube
Find the unit - price by dividing the total price by the number of ounces. For the 5 - ounce tube, the unit - price $u_1=\frac{3.39}{5}= 0.678$ dollars per ounce.
Step2: Calculate unit - price of 4 - ounce tube
For the 4 - ounce tube, the unit - price $u_2=\frac{2.80}{4}=0.7$ dollars per ounce.
Step3: Compare unit - prices
Since $0.678<0.7$, the 5 - ounce tube has a lower unit - price.
Answer:
The 5 - ounce tube of toothpaste for $3.39 is the better buy.
