To find the total number of visitors who came to the art show on both Friday and Saturday, we start with the number of visitors on each day.
-
Calculate the number of visitors on Saturday:
- We know that on Friday, 92 visitors came.
- On Saturday, there were 24 fewer visitors than on Friday, so we can calculate the number of visitors on Saturday as follows: \[ \text{Visitors on Saturday} = \text{Visitors on Friday} - 24 = 92 - 24 = 68 \]
-
Calculate the total number of visitors for both days:
- Now we add the number of visitors from Friday and Saturday: \[ \text{Total visitors} = \text{Visitors on Friday} + \text{Visitors on Saturday} = 92 + 68 = 160 \]
Therefore, the total number of visitors who came to the art show on Friday and Saturday combined is \( \boxed{160} \).
