How long (in years) would $700 have to be invested at 11.9% compounded continuously to earn $300 interest?​

A = Pert is formula for continuously compounded interest

A = final amount = 2000

P = principal = 1000

e = euler's number (on calculator)

r = interest rate as decimal = .075

t = time in years

Your mistake is that 7.5% as a decimal is 7.5/100 = .075

not 7.5

2000 = 1000e.075t

e.075t = 2000/1000

e.075t = 2

take natural log of both sides

ln e.075t = ln 2

.075t = ln 2

t = ln2/.075

t = 9.24 years

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
