No it’s not. a quadratic formula has x^2 as the highest value(?). the highest exponent here is 3x^4. it’s called a quartic polynomial
So
x=earned
x>200
they paid their parrents 28 for supplies (this assumes that they paied 28 altogether and not 28 each)
so subtract 28 from pay
new pay=y
y>200-28
y>172
divided it among themselves (3)
172/3=57 and 1/3=57.33
they each earned more that $57.33
