Amount owed by Wang = $8500

Let the amount paid by him each month be = x

Remaining debt after 12 months = $6460

Hence, Wang had paid = in 12 months

Let us assume that Wang paid the same amount per month for 12 months

So, he paid =

Wang paid each month $170.

Assuming that he paid the same amount every time till all the money is paid, so time taken to pay entire amount of $8500

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
