Question

Jed is pouring water into a container at a constant rate of 8.25 ounces per second. There are already 24.75 ounces of water in a container. How many

ounces of water will be in the container after 5 seconds?
29.75 ounces
33 ounces
49.5 ounces
66 ounces

Answer 1

66 ounces

Explanation:

To solve this, set up a fraction. Let "x" be the ounces of water after 5 seconds.

`(8.25)/(1)=(x)/(5)`

Step 1: Switch sides

`(x)/(5)=(8.25)/(1)`

Step 2: Apply rule:
`(a)/(1)=a`

`(x)/(5)=8.25`

Step 3: Multiply both sides by 5

`(5x)/(5)=8.25\cdot \:5`

Step 4: Simplify

`x=41.25`

Now we have found the ounces of water in the container after 5 seconds, but already, there are 24.75 ounces before the ounces after 5 seconds. So to find the total add the given data to the found result

Step 1: Add 24.75 to 41.25

`24.75 + 41.25 = 66`

Therefore, there are 66 ounces after 5 seconds when 24.75 ounces are already in the container.

Answer 2

66 ounces

Explanation:

24.75 + (8.25 x 5) = 24.75 + 41.25 = 66
