See attached graph
Step-by-step explanation:
The graph of distance from home as a function of time starts at the origin of coordinates (0,0) since at time zero minutes Varun is at home.
Then we represent his driving at constant speed (although it has not been specified in the problem) as a line with positive slope equal to his speed, that goes on for the first five minutes. After that, he reaches the traffic light that keeps him at the same distance from home for three minutes (notice the line representing the distance covered is flat from minute 5 to minute 8, while he is not moving).
Then he starts moving again (we assume at the same speed as before - so the line representing his position is again a line with positive slope and with the SAME inclination as that which represents the first 5 minutes of his trip.
The line ends at minute 15 which is the time it took him to get to work.
The amount of interest he would earn in one (1) year is equal to $80.
<u>Given the following data:</u>
- Interest rate = 10% = 0.1
- Principal = $800
- Time = 1 year
To determine how much interest he would earn in one (1) year:
<h3>How to calculate simple interest</h3>Mathematically, simple interest is given by this formula:
<u>Where:</u>
- S.I is the simple interest.
- P is the principal or starting amount.
- R is the interest rate.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;
Simple interest = $80
