An office manager booked 61 airline tickets. He booked 8 more tickets on Airlines A than Airlines B. On Airlines C, he booked 5 more than twice as many tickets as on Airlines B. How many tickets did he book on each airline?
61 tix = B + B+ 8 + 2B+5 solve for B then A = B+8 C = 2B+5
We first denote b as the total number of tickets booked on airline b, we construct the following equation:
So on airline b he booked 12, on a he booked 20, and on c he booked 29.
