Borris liquor store uses 90 kilograms of grapes every 6 months. He is thinking of increasing his production by twenty percent. How many grapes does he need in a year after increasing his production?
Borris uses 90 x 2 = <T>multiply(90, 2)=180 kilograms of grapes per year.
The increase of kilograms of grapes he needed per year is 180 x 0.20 = <T>multiply(180, 0.2)=36.0
Therefore, Borris needs 180 + 36 = <T>add(180, 36)=216 kilograms of grapes in a year.
