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

Answer:

each hour 24 bottles are rejected

Step-by-step 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

$\frac{100}{5} =\frac{x}{60}$

isolating x

$\frac{60*100}{5} =x\\x=1200$

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%

$\frac{1200}{100} =\frac{x}{2}$

isolating x

$\frac{1200*2}{100} =x\\x=24$

in an hour 24 bottles are rejected

Have a great day
