Answer:
x = 15
Step-by-step explanation:
given that y varies directly with x
mathematically we can express this as
y = k x , where k is a constant
step 1: find k
given x = 3 and y = 21
y = k x
21 = k (3)
k = 7
hence the equation becomes
y = 7 x
when y = 105,
105 = 7x
x = 105 / 7 = 15
Answer:6/5+6x
Step-by-step explanation:multiply 3 by 2/5 and 15x by 2/5

Cost=$225
Revenue = $75x, x being the number of rooms rented.
R-C=75(35)-225=$2400
Double that
4800=75*x-225
5025=75x
x=67 rooms
One can't just double the number of rooms, because the maintenance fee is constant and doesn't change proportionally. It doesn't change at all.
