Total Pop minus non-eligible tourists:
150 - 40 = 110, or the amount of tourists who have visited at least Mexico or Jamaica
I pictured the next step in the context of a Venn Diagram, in which we have two circles representing tourists who traveled to Mexico (105) and Jamaica (34). This approach is similar to solving probability in the context of a Venn diagram.
Let's examine what we know. We know that there are 110 eligible tourists who have traveled to either Mexico or Jamaica. And since the total of all tourists traveling to Mexico and Jamaica is 105 + 34 = 139, we know there is some overlap here. So what's the overlap? 139 - 110 = 29. In other words, 29 tourists have traveled to both Mexico and Jamaica.

Subtract 25 from 105 & 34 so 80+25+9+40>150 therefore the common set will be greater than 25 cannot be below 25. So A boom
