In the U.S., we represent money values with dollars and cents. There are 100 cents in a dollar. Amounts of money are represented with at most two decimal places (Ex: $4.25). Gas prices are often shown to have more than two decimal places. A gallon of gas costs $3.3842 at Buc-ee's in Daytona Beach, Florida. Use this gas price to round the gas price to the nearest cent (hint: the nearest cent is the hundredths place). (1 point)

Question

In the U.S., we represent money values with dollars and cents. There are 100 cents in a dollar. Amounts of money are represented with at most two decimal places (Ex: $4.25). Gas prices are often shown to have more than two decimal places. A gallon of gas costs $3.3842 at Buc-ee's in Daytona Beach, Florida. Use this gas price to round the gas price to the nearest cent (hint: the nearest cent is the hundredths place). (1 point)

Question 2
You need to stop for gas at Buc-ee's and your car has a gas tank that will hold 14.25 gallons. It is on empty. How much will it cost to fill up the tank using the rounded price of gas from the previous question? You will need to round your cost to the nearest cent. (1 point)

Question 3
Express the price per gallon of gas as a mixed number. Use $3.38 as the price. (You can use the ∑ symbol to type in a fraction). (1 point)

Answer 1

$3.38 can be expressed as a mixed number as $3 and 38/100, or $3 38/100.

Answer 2

To round the gas price to the nearest cent, we need to look at the hundredths place.

The hundredths place in the given gas price of $3.3842 is 4. Since 4 is less than 5, we round down and keep the digits before the hundredths place unchanged.

Therefore, the rounded gas price to the nearest cent is $3.38.

Now, to calculate the cost of filling up the tank, we need to multiply the rounded gas price by the number of gallons.

$3.38 * 14.25 = $48.2175

Since we need to round the cost to the nearest cent, we look at the hundredths place (7). Since 7 is greater than or equal to 5, we round up the tenths place to the next whole number.

Therefore, the rounded cost to fill up the tank using the rounded gas price is $48.22.

So the correct answer for Question 2 is:

$48.22

Now, let's move on to Question 3.

To express the price per gallon of gas as a mixed number, we need to divide the price by 1 dollar (100 cents) to separate the whole number part and the fractional part.

$3.38 divided by $1 can be represented as 338 cents divided by 100 cents.

Thus, the price per gallon of gas as a mixed number is 3 and $\frac{38}{100}$ or simply 3 $\frac{19}{50}$.

So the correct answer for Question 3 is:

3 $\frac{19}{50}$

Answer 3

To round the gas price to the nearest cent, you need to look at the number in the hundredths place. In this case, the gas price is $3.3842. The number in the hundredths place is 4. Since it is less than 5, you round down. Therefore, the gas price rounded to the nearest cent is $3.38.

To calculate the cost of filling up a 14.25 gallon tank, you multiply the number of gallons (14.25) by the rounded gas price ($3.38). The calculation is 14.25 x 3.38 = 48.165. Now, since the question asks us to round the cost to the nearest cent, we look at the number in the hundredths place, which is 5. Since 5 is equal to or greater than 5, we round up. Therefore, the cost to fill up the tank is rounded to $48.17.

To express the price per gallon of gas as a mixed number, you divide the price ($3.38) by 1. You can write $3.38 as 3 + 0.38. The fraction 0.38 is equivalent to 38/100. So, the mixed number representation would be 3 + 38/100, which can be simplified to 3 + 19/50.
