Victor, Leo, and Kate together sold 87 tickets for the school banquet. Victor sold 32 tickets and Leo sold 26 tickets. How many tickets did Kate sell?

29

58

First you have to add Victor and Leo's tickets. 32+26=58 then you have to take 87 and subtract it by 58. 87-58=29 Kate sold 29. What I did was figure out what Victor and Leo sold and added it together then took their tickets out of the whole so the only one left is Kate's.
