Question

The truckshop orders 200 bottles of juice a week. If 22% are sold on Tuesday then
a) What percentage is left?
b) How many bottles have been sold

Answer 1

a) 78% is left
b) 44 bottles have been sold

First of all, we know that everything is 100% if full and since 22% was sold, we subtract 22 from 100 which gives you 78% remaining

Secondly, to find the the total bottles sold, we convert 22%into a decimal which gives you 0.22.
Finally, we multiply 0.22 by 200 which gives us 44 bottles sold
