Answer:
The travel size costs 6.24 % as much as the regular size. Thus the regular size would be more economical and thus a better buy.
Step-by-step explanation:
1. To calculate the price per ounce, for the regular tube toothpaste we can express this as;
Total price of regular tube toothpaste=Price per ounce×Number of ounces
where;
Total price of regular tube toothpaste=$2.50
Price per ounce=x
Number of ounces=3.2 ounces
replacing;
2.50=x×3.2
x=2.5/3.2
x=0.78125
Price per ounce=0.78125 dollars/ounce
2. To calculate the price per ounce, for the travel size tube toothpaste we can express this as;
Total price of regular tube toothpaste=Price per ounce×Number of ounces
where;
Total price of regular tube toothpaste=$1.00
Price per ounce=x
Number of ounces=1.2 ounces
replacing;
1.00=x×1.2
x=1/1.2
x=0.83
Price per ounce=0.83 dollars/ounce
3. How much more the travel size costs than regular;
((Travel size costs-Regular size cost)/(regular size cost))×100
((0.83-0.78125)/0.78125)×100
(0.04875/0.78125)×100=6.24 %
The travel size costs 6.24 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
