Mhm thats most definitely a trick question .
Answer:
B
Step-by-step explanation:
Answer:
$ 9
Step-by-step explanation:
Simple Interest = P.R.T / 100
P = Principal (Amount invested) =$30
R = Rate= 10%
T = Time = 3 years
Therefore, Simple Interest (I):
I = PRT/100
I = ($30 * 10 * 3 ) / 100
I = $900 / 100
I = $9
She will have a total of $9 in three years
We assume a linear system with 2 variables.
If the slopes are the same, and y-intercepts are different, there are 0 solutions.
If the slopes are different, there is 1 solution.
If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.
