Given:

Laura has 160 pounds of green beans at her vegetable stand.

She sells 10 pounds of green beans every hour.

To find:

The percent decrease in green beans after 3 hours.

Solution:

We have,

Beans sold in 1 hour = 10 pounds

So, Beans sold in 3 hours = 30 pounds

Decrease in green beans after 3 hours is 30 pounds.

Now,

\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100

\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100

\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}

\%\text{Decrease in green beans after 3 hours}=18.75\%

Therefore, the correct option is A.
