Question

a bottling company can fill 100 bottles in 5 minutes, 2% of the bottles are rejected, how many bottles are rejected each hour?

Answer 1

2% of 100 is 2. There are 60 minutes in an hour. 60/5=12. 12×2=24.

24 bottles are rejected each hour.

Answer 2

each hour 24 bottles are rejected

Explanation:

Hello

Step 1

first, we need to know how many bottles are filled in an hour

60 min=1 hour

using a rule of three

5 minutes⇔100 bottles filled

60 minutes⇔x bottles filled

`(100)/(5) =(x)/(60)`

isolating x

`(60*100)/(5) =x\\x=1200\\\\`

in an hour 1200 bottles are filled

Step 2

2% of the bottles are rejected, how many bottles are rejected each hour?

we need to know the 2% of 1200, using a rule of three

1200 bottles⇔100 %

x bottles?⇔2%

`(1200)/(100) =(x)/(2)`

isolating x

`(1200*2)/(100) =x\\x=24\\\\`

in an hour 24 bottles are rejected

Have a great day
