​Simple Interest

7th Math Module 2​

Simple Interest

Objective: I will solve problems involving simple interest

Vocabulary

• Simple Interest: A one time fee charged for borrowing money.

• I = (P) (R) (T)

• I = Interest

• P = Principal

• t = Time (expressed in months)

​Simple Interest

I = P x R x T

When in real life do we have interest with our money?​

Some text here about the topic of discussion

​Simple Interest

I = P x R x T

I= Interest earned

P= Principal: money borrowed or deposited (Starting amount)

R= Rate: Always in decimal form (7%= .07)

T= Time: Always in years (5 years = 5 or 6 months=0.5 years)​
