Use the Rule of 72:
How many years will it take to double my money? (r is interest rate)
72 𝑟 = Years to double any amount of money
At what interest rate will my money double in a set number of years? (y is number of years)
72 𝑦 = Interest Rate needed
r must be in number format. examples: write 6% as 6, 0.15 (with no %) is 15

13. Calculating Interest (Accurately)
Simple interest means that interest is calculated after a set period of time.
I = interest
r = interest rate
P = principal amount
t = time
SIMPLE INTEREST
𝐼=𝑃 ×𝑟 ×𝑡
ex: 𝐼= $1,000 × 6% annual rate × 6 months
How would we write the formula?
𝐼=$1000 ×0.06 ×0.5
How much interest was earned?
r and t must be in the same unit of measurement ex: interest per year and number of years

14. Using “Prt” Remember: 𝐼=𝑃 ×𝑟 ×𝑡
How much interest will Bill’s savings account accrue in a year, if his account balance is $4200 and the interest rate is 8% per year?
In one year, how much interest will Patty’s account with an account balance of $230,000 earn at an interest rate of 0.85% per month?
If George wants his account balance of $8 million to reach $10 million in 2 years, what interest rate must he receive?
