Answer:
9
Step-by-step explanation:
3x + 3 = 30
-3 -3
3x = 27
/3 /3
x= 9
The answer is none of these
50 would be a good choice of answer
3% interest on 5,000 = 150
275 (the total amount wanted) - 150 (from initial investment)= 125
x (5%) =125
x (0.05)= 125
x/0.05)= 125/0.05
x=2500
you need to invest 2500 at 5% to get the additional 125
125 plus 150= 275
