one third of number is: n/3

decreased by 36 is: n/3 - 36

is at most 22: n/3 - 36 <= 22

so,

n/3 - 36 <= 22

n/3 <= 58

n <= 174

--------------------

cost for n tickets: 55 + .15n

revenue: 1.25n

profit is when revenue > cost:

1.25n > 55 + .15n

1.1n > 55

n > 50

check:

cost for 50 = 55 + 7.50 = 62.50

revenue for 50 = 1.25 * 50 = 62.50
