Rob borrowed $2500 for 18 months and repaid $ 2950. What simple annual interest did he pay?

Answers

He payed a lot of interest

Using the simple interest rate formula, Rob paid 12% of simple annual interest.

What is simple interest?Simple Interest is a method of calculating interest that is earned for a principal amount at some rate of interest for a particular time. It is a simple method for figuring out a loan's interest rate. It is calculated by dividing the principle by the daily interest rate and the number of days between payments.

So, the principal amount is $2500.

The time is 18 months.Rob repaid $2950.Simple interest formula:Simple interest = Amount - principal

Now, calculate as follows:

Simple interest = Amount - principalSimple interest = 2950 - 2500Simple interest = $450

Now,

18/12 = 3/2Simple interest = 100/ time × principal $450 = 100 × 2/3 × $2500 12 %

Therefore, using the simple interest rate formula, Rob paid 12% of simple annual interest.

HELP PLZ FAST Neil has been running a tutoring business since 2015. He charges a monthly fee for weekly tutoring sessions and a phone help line. Each year, he has increased his fee by the same amount. The table shows what Neil charged each customer for two given years of his business:

Year Annual Tutoring Fee
2015 $1140
2018 $1350
A. What is the rate of change and initial value for Neil's business? How do you know? (2 points)
B. Write an equation in slope-intercept form to represent the fees that Neil charges each year since 2015. (3 points)

Answers

Answer:

Rate of change is the same as slope in this case.

(1350-1200)/(2008-2005) = 150/3 = $50 increase per year

The initial amount he started charging was $1200 a year.

y = 50x + 1200, where x represents the number of years since 2005.
