Suppose Isabel places $3500 in an account that pays 19% interest compounded each year, Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding,

(a) find the amount in the account at the end of 1 year

(b) find the amount in the account at the end of 2 years

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)

correct answers below:

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
