Answer:
80 rooms
Step-by-step explanation:
since 45% of the rooms are booked, and 36 rooms are booked, then this means that 36 = 45% of x.
then, you we have 45% × x = 36
or [tex]\frac{45}{100}[/tex] × x = 36
Multiplying both sides by 100 and dividing both sides by 45,
we have x = 36 × [tex]\frac{100}{45}[/tex]
= [tex]\frac{3600}{45}[/tex]
x = 80
