Lisa, a real estate agent, earned a Big commission for selling a house. If she puts the money into an account that earns 11.32% interest compounded continuously, how long will it take for her money to double? Round your answer to the nearest month.

6 years and 1 month

Step-by-step explanation:

A= Pe^rt

Since you need to find the double A=2P

2P=e^0.1132t

0.1132t=ln 2

0.1132t=0.693

t= 6.12

6 years and 1 month

ps: I think this is right but I'm not sure I had the same problem and I got this.

answer: i guess 5 units?

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
