Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless services. Determine whether each customer should receive a new contract as follows: a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.

Solution :

'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.

Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true.  If one of the P or Q is not true, then outcome result will be false.

In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.

Therefore, using the AND operation of the customers as :

Customer     Wireless     Discount     Outcome

   A                   N                   N             FALSE

   B                   Y                   N             FALSE

  C                   N                   Y              FALSE

   D                   Y                   Y             TRUE
