Amusement park?

0 ⤊

85 children went to an amusement park where they could ride on the merry-go-round, roller coaster and ferris wheel. 20 of them took all 3 rides and 55 of them took at least 2 of the 3 rides. Each ride costs $1 and the total receipts from the group were $145. How many children did not try any ride?

20 kids took 3 rides= $60
35 kids took 2 rides= $70
15 kids must have taken 1 ride=$15
Since that totals $145 and accounts for 70 kids,then I would think 15 kids didn't take any ride.
