128 classes visited the exhibit in both days
Explanations:The number of classes that visited the exhibit on Friday = 32
Let the number of classes that visited the exhibit on Saturday be y
Three times as many classes visited on Satuday than on Friday
y = 3 x 32
y = 96
96 classes visited the exhibit on Saturday
The total number of classes that visited the exhibit in both days = 96 + 32
The total number of classes that visited the exhibit in both days = 128
