In order to find the inverse of this conditional, we need to negate both the first and second statement.
So we have:
First statement: "Tracy is not going to Quinn's candy shop"
Second statement: "she is not going to buy sour straws"
Negating these, we have:
First statement: "Tracy is going to Quinn's candy shop"
Second statement: "she is going to buy sour straws"
So the inverse will be:
"If Tracy is going to Quinn's candy shop then she is going to buy sour straws."
