Expert Answer
If there are 8 ways to perform task A and 80 ways to perform task A and then task B, we can calculate the number of ways to perform task B alone by subtracting the number of ways to perform task A and task B from the total number of ways to perform task A.Let's assume that there are x ways to perform task B alone.Therefore, the number of ways to perform task A and then task B is 80. The number of ways to perform task A is 8.
