if you bought a stock last year for a price of $120 and it has gone down 10% since then how much is the stock worth now

$108

Step-by-step explanation:

Since $120 is divisible by ten, we can just simply do 120/10, which is twelve. So, 10% of $120 is $12. $120 - $12 = $108

d is correct

step-by-step explanation:

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)
