900%2A+2%5Et+
That should work. You agree that after 1 hour it would have doubled, 2 hours quadrupled, 3 hours increased 8 times, etc:
2%5E1+=+2+
2%5E2+=+4+
+2%5E3+=+8+
:
:

so, 900%2A+2%5Et+ ...plug in given values for t
after 1 hour it would have 900%2A+2%5E1=900%2A2=1800+
after 2 hour it would have 900%2A+2%5E2=900%2A4=3600+
after 3 hour it would have 900%2A+2%5E3=900%2A8=7200+
after 5 hour it would have 900%2A+2%5E5=900%2A32=28800+
