Well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.
1 bed room = 12
2 bed room = 15
68 x 15 = 1020
57 x 12 = 684
-----------
1020 + 684 = $1704 (total made)
15 two-bed room + 12 one-bed room = 27 rooms in all

Answer:
2
Step-by-step explanation:
For any positive numbers a,b we always have the following identity:

(gcd(a,b) denotes the greatest common divisor between a and b, and lcm(a,b) denotes the least common multiple between a and b)
In our case, we are given that
and that
. Plugging that in into our identity, we get:

And so solving for
:
