In 1984, a 12-ounce box of cold cereal cost $0.89. In 2008, an 18-ounce box of the same cereal sold for $3.29. How much more was the cost of the cereal per ounce in 2008 than in 1984? Explain

Answers

Answer 1
Answer: Well, we can just divide them.

0.89 / 12 is approximately $0.07

3.29 / 18 is approximately $0.18

0.18 - 0.07 = $0.11

So the cost of cereal in 2008 is 11 cents more per ounce than the cereal in 1984.
Answer 2
Answer: Firstly we need to find out how much is worth 1 ounce of cold cereals both in 1984 and 2008. Do do that we may just divide both numbers by 12:

0.89 ÷ 12 ≈ 0.07 (I rounded it to the neaerest cent as we're talking about money anyway)
3.29 ÷ 18 ≈ 0.18

So in 1984 one ounce costed $0.07, while in 2008 it costed $0.18.

To find out how much more was it in 2008, we just need to do the substraction:

$0.18 - $0.07 = $0.11

Answer: The cost of the cereals per ounce was bigger in 2008 than in 1984 by $0.11.

Write the greatest whole number that uses all the digits from 1 to 9.

Answers

we know that

The way to form the greatest number is to use the highest valued digit in the most significant digit.

so

900,000,000+80,000,000+7,000,000+600,000+50,000+4,000+300+20+1=987,654,321

therefore


the answer is

The greatest whole number that uses all the digits from 1 to 9 only at once is

987,654,321
987,654,321 would be the greatest WHOLE number using the digits 1-9 only once i assume

Step-by-step explanation:

The formula of a volume of a cone:

V=(1)/(3)\pi r^2H

r - radius

H - height

We have r = 1.9 in and H = 15 in. Substitute:

V=(1)/(3)\pi(1.9)^2(15)=\pi(3.61)(5)=18.05\pi\ in^3

\pi\approx3\to V\approx18.05\cdot3=54.15\ in^3
