Answer :
let x - number of $26 tickets
y- number of $40 tickets
x + y = 5000
x = 5000 - y
26x + 40y = 155,200
26(5000 - y) + 40y = 155200
130,000 - 26y + 40y = 155200
14y = 25,200
y = 1800
x = 5000 - 1800 = 3200
let x - number of $26 tickets
y- number of $40 tickets
x + y = 5000
x = 5000 - y
26x + 40y = 155,200
26(5000 - y) + 40y = 155200
130,000 - 26y + 40y = 155200
14y = 25,200
y = 1800
x = 5000 - 1800 = 3200
