Question

8.25 The glass gauge on a cylindrical coffee maker shows there are 45 cups left when the coffee maker is 36% full. How many cups of coffee does it hold when it is full?

Answer 1

125 cups

Explanation:

36/100*x = 45

18/50*x = 45

18x = 2250

x = 125

Answer 2

The amount of coffee the maker will hold when full be 125 cups.

Explanation:

Given:

• The glass gauge on a cylindrical coffee maker shows there are 45 cups left when the coffee maker is 36% full.

To find:

• Number of cups of coffee does it hold when it is full.

The formula used to calculate percentage is: (value/total value)×100%.

Step 1 of 1

Let the amount of coffee the maker will hold when full be x.

Then given the glass gauge on a cylindrical coffee maker shows there are 45 cups left when the coffee maker is 36% full.

Which implies:

`$$\begin{gathered}(36)/(100) * x=45 \\0.36 x=45 \\x=(45)/(0.36) \\x=125\end{gathered}$$`
