Answer:
<em>Interest = $3,888</em>
Step-by-step explanation:
Formula:
I = prt or I = p · r · t
what it stands for:
I = amount of interest
P = principal amount ($1,200)
R = interest rate (in years)(3% into decimal which would be .03)
T = amount of time (in years)($108)
so:
I = prt
I = (1,200)(.03)(108)
I = $3,888
Interest = $3,888
For 1 hour, money = $20
For $140, it would be: 140/20 = 7 hours.
So, option C is your final answer.
Hope this helps!
Since M is parallel to N that means they would have to equal each other.
