An investor invested a total of $3 comma 500 in two mutual funds. One fund earned a 4% profit while the other earned a 2% pro

lesya [120]

Answer:

$2000 invested in first fund

$1500 invested in second fund

Step-by-step explanation:

An investor invested a total of $3,500 in two mutual funds.

Let x be the amount invested in first fund

first fund earned a 4% profit (4%= 0.04)

So interest is 0.04x for first fund

Let x be the amount invested in first fund

first fund earned a 4% profit (4%= 0.04)

So interest is 0.04x for first fund

Let y be the amount invested in second fund

second fund earned a =2% profit (2%= 0.02)

So interest is 0.02y for second fund

An investor invested a total of $3,500 in two mutual funds.

So x+y = 3500----> equation 1

y= 3500-x

the investor's total profit was $110

0.04x + 0.02y = 110----> equation 2

Plug in 3500 -x for y

0.04x + 0.02(3500-x) = 110

0.04x + 70 - 0.02x = 110

0.02x + 70 = 110

Subtract 70 onboth sides

0.02x = 40

Divide both sides by 0.02

x= 2000

y= 3500-x

so y= 3500 - 2000 = 1500

$2000 invested in first fund

$1500 invested in second fund
