Answer:
$9000
Step-by-step explanation:
Let a and b represent the amounts invested in the two funds. The problem statement gives two relations:
a = 2b . . . . . . the amount invested in A was twice that invested in B
7%×a +3%×b = 1530 . . . . . the total profit from the two funds
Substituting for a in the second equation, we have ...
0.07(2b) + 0.03b = 1530
0.17b = 1530 . . . . . . . . . . collect terms
1530/0.17 = b = 9000
Deandre invested $9000 in Fund B.
Expand and multiply
3^5 = 3 x 3 x 3 x 3 x 3 = 9 x 9 x 3 = 81 x 3 = 243
243 is your answer
hope this helps
