You are saving money to buy an electric guitar. you deposit $1000 in an account that earns interest compounded annually. the expression 1000(1+r)^2 represents the balance after 2 years where r is the annual interest rate in decimal form. write a polynomial in standard form. the interest rate is 3%. what is the balance of your account after 2 years. the guitar costs $1100. do you have enough money in your account after 3 years?

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
