Question

On average, 24% of customers who buy shoes in a particular store buy two or more pairs. One weekend 350 customers purchased shoes. How many can be predicted to buy two or more pairs? If 107 customers buy more than two pairs, did more customers than normal buy two or more pairs?

Answer 1

To predict how many customers out of the 350 will buy two or more pairs, you need to find 24% of the 350 customers: 24% * 350 = 84 Customers. So, it is predicted that 84 customers will buy a second or more pair.

However, 107 customers bought a second pair. To find how many more from the predicted amount, you need to find the difference: 107 - 84 = 23 customers. So, 23 more customers bought a second pair than the predicted amount (of 84).

Therefore, yes, more customers than norma bought two or more pairs. 


Hope this helps. :)
