Answer:
1,500 beds
Explanation:
Occupancy rate shelter A = 300 x 20/100 = 60
Let capacity of shelter B be X
60% occupancy ==> 60/100 x X = 0.6X
Occupancy rate of A to rate of B is 1: 15 can be expressed as fraction 1/15
Therefore
60/0.6X = 1/15
1 x 0.6X = 60 x 15
0.6X = 900
X = 900/0.6 = 1,500 beds
