Nick has 31 coins, make up of quarters, nickels, and dimes. if he had one more dime, he would have just as many dimes as he has nickels and quarters put together. if the total value of nick’s coins is $4.70, how many coins of each does he have?

step-by-step explanation:

(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)
