A bank loaned out $6,000, part of it at the rate of 15% annual interest, and the rest at 7% annual interest. The total interest earned for both loans was $740.00. How much was loaned at each rate?

step-by-step explanation:

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)

5 x 14?

im new, sorry if this is wrong.
