Let's say o is the height of an ostrich and k is the height of a kiwi.
4k is four times the height of a kiwi.
4k + 20 is 20 inches more than 4 times the height of the kiwi, so
o = 4k + 20.
I can't solve this without knowing the height of the ostrich, so if you have that comment and I'll edit the answer.
X = # of perfomances
y = total amount of money
Income: y = 7500x
Expense: y = 5900x + 88000
Substitution:
7500x = 5900x + 88000
1600x = 88000
x = 55
y = 7500(55) = $412,500
55 performances are needed to break-even.
