Answer 1

Amount invested in account A: $3,250

Amount invested in account B: $1,750

Explanation:

Let x = the amount invested in account A

y = the amount invested in account B

So now you have 2 equations:

x + y = 5,000 ---> x = 5,000 - y

0.02x + 0.04y = 135

Substitute x = 5,000 - y into 0.02x + 0.04y = 135

0.02(5,000 - y) + 0.04y = 135

100 - 0.02y + 0.04y = 135

100 + 0.02y = 135

0.02y = 35

y = 1750

x = 5000 - 1750

x = 3250

Amount invested in account A: $3,250

Amount invested in account B: $1,750
