Answer:

$2400

Step-by-step explanation:

The question is asking the amount invested in fund B. We can let 'b' represent that amount. Then the amount invested in fund A is (6000-b). The total profit from the investments is ...

0.02(6000 -b) +0.07(b) = 0.04(6000)

120 +0.05b = 240 . . . . . simplify

0.05b = 120 . . . . . . . . . subtract 120

b = 2400 . . . . . . . . . . .divide by 0.05

Alonzo invested $2400 in fund B.
