Answer:
The regular size is more economical.
Step-by-step explanation:
Consider the provided information.
A regular tube of toothpaste costs $2.50 for 3.2 ounces.
Find out the unit rate as shown below:

Therefore, the cost of one ounce is $0.78.
A travel size tube costs $1.00 for 1.2 ounces.
Find out the unit rate as shown below:

Therefore, the cost of one ounce is $0.833.
From the above calculation we can observe that regular tube toothpaste price is better buy.
Now find the percent as shown:
Firs find the difference
$0.83-$0.78 = $0.05
Therefore,

Hence, regular tube is 6.41% less costly as compare to travel size.
