Let the unknown number be "n",
This number is sutracted from 46. So, 46 less n.
That is (46 - n).
The result to this is -21.
∴The equation would be;
46 - n = -21.
Now solve for n.
46-n=-21
46 + 21 =n
∴n=67
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
