@Aminu your question is incomplete. Just as sub5 has said, what was the initial amount or the first amount of money given to her?  :wonder:

ok Aminu, if 2 Naira was the initial amount given to her, i will say let the days be equal to x

The amount which will be double on daily basis, i will say x2
Therefore the total amount will be
 x2 + x4 + x8 + x16 + x32 + x64 + .....................x1073741824

Now if we add the total amount of money she collected we will have

2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096 + 8192 + 16384 + 32768 + 65536 + 131072 + 262144 + 524288 + 1048576 + 2097152

+ 4194304 + 8388608 + 16777216 + 33554432 + 67108864 + 134217728 + 268435456 + 53687012 + 1073741824

The total amount that the girlfriend recieved at the end of the 30 days is equal to 1,664,299,746 Naira
