Answer:
Step-by-step explanation:
Suppose that at time  we have x mold cells. We are told that after 12 minutes the amount present is double. That is a
 we have x mold cells. We are told that after 12 minutes the amount present is double. That is a  we have 2x cells. Then, at
 we have 2x cells. Then, at  we have (2x)*2 = 4x. We can continue as follows
 we have (2x)*2 = 4x. We can continue as follows 
 we have (4x)*2 = 8x.
 we have (4x)*2 = 8x. 
 we have (8x)*2 = 16x
 we have (8x)*2 = 16x
 (one hour later) we have (16x)*2 = 32x.
 (one hour later) we have (16x)*2 = 32x. 
So after one hour from now we have 32x cells.
