A Florida factory produces fishing reels at a rate of 800 per day, every day. In April, they are forced to cut their production
Bingel [31]

Multiply 800 to 4/5 to see how much they make per day.

800 * 4/5 = 640

So, they make 640 fishing reels per day.

Multiply this to 30:

640 * 30 = 19,200

So they will make 19,200 fishing reels in 30 days.

This is not enough for the order.
