Given:
Rate of simple interest = 5%
Time = 4 years
Total interest = $160
To find:
The amount borrowed by Austin from a credit union.
Solution:
The formula for simple interest is:

Where, P is principal, r is the rate of interest and t is the number of years.
Putting
in the above formula, we get



Multiply both sides by 5.

Therefore, Austin borrowed $800 from a credit union for 4 years.
slope intercept form = y=mx +b
where m would be the slope and b is the y intercept
equations would be:
cool cars: y = 179x +1999
awesome autos: y = 249x
