If the federal budget for 2007 was 2.8 trillion dollars, how much money did the government spend per second? Please help!
diamong [38]

Solution:

we are given that

The federal budget for 2007 was 2.8 trillion dollars.

we have been asked to find

how much money did the government spend per second?

First we will find the number of seconds in one year

Number of seconds in 1 year=365*24*60*60=31536000 Seconds

Now we will dive the amount by the total number of seconds, we get

\frac{2,800,000,000,000}{31536000} =88787.41755 dollar

Hence the government is spending approximately 88787 dollars per second.

A 16−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 t
LUCKY_DIMON [66]

Answer:

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!
