A16−oz bottle of parmesan cheese costs $5.78, while an 8−oz bottle costs $3.97. which is the better buy? round your answer to the nearest cent if necessary

The 16-oz bottle of parmesan cheese is the better buy.

Step-by-step explanation:

Even though 8-oz is half the amount of 16-oz, that doesn't mean it's cheaper. Let's find the amount of and 8-oz bottle when a 16-oz bottle is $5.78:

16-oz bottle of parmesan cheese = $5.78

A price of an 8-oz bottle when 16-oz is divided by 2:

16 ÷ 5.78 = $2.76

The original price of the 8-oz bottle should've been $2.76 but it's more expensive due to VAT.

So the 8-oz bottle is more expensive, therefore the 16-oz bottle is the better buy!

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
