Question

A bank prefers to maintain a ratio of three customers to one teller. If there are nine customers in the bank, how many tellers should be available to meet this ratio?

Answer 1

To maintain the preferred ratio of three customers per teller, divide the number of customers (9) by the ratio (3), resulting in 3 tellers needed for nine customers. Thus, the bank should have three tellers available to serve the nine customers in order to keep the preferred 3:1 customer to teller ratio.

Step-by-step explanation:

The student's question requires an application of the concept of ratios.

In order to maintain a ratio of three customers to one teller, we need to divide the number of customers by three. For nine customers, we have:

Number of tellers = Number of customers ÷ Ratio of customers to tellers

Number of tellers = 9 ÷ 3

Number of tellers = 3 tellers

Thus, the bank should have three tellers available to serve the nine customers in order to keep the preferred 3:1 customer to teller ratio.
