The Hortex company produces bottled carrot juices. Every day it can produce 4200 bottles of these juices. Each juice can cover 20% of 1 person'ts daily energy demand. How many more bottles of juices would Hortex have to produce to be able to satisfy 100% of the daily energy needs of 2300 people?
Each juice covers only 20% of the daily energy demand, so to cover 100%, one person would need 100 / 20 =

5 juices.
So 2300 people, need 5 * 2300 = 
<gadget id="calculator">2300*5</gadget>
<output>11_500</output>
11500 juices for this purpose.
To cover 100% of the daily energy needs of 2300 people, Hortex would need to produce 11500 - 4200 = 7300 bottles of juices.
