The history museum is hosting a special exhibition on history of flight. The admission ticket for each adult costs $3 and the ad

mission ticket for each child costs $2. On the opening day of the exhibition, 60 tickets were sold for a total of $160. How many adults visited the special exhibition?

Since it does not give us any specifications as to the exact numbers, we can assume that the amount of adults ranges from 32 to 40, as these are the only numbers that are whole when divided. Obviously, we can't have 24.3333 of a person, so we have our range of answers.
