Question

Alexa invests $7900 in two different accounts. The first account paid 6% simple interest, and the second

account paid 4% simple interest. At the end of the year, she earned $368 in interest. How much was
invested in each account?

Answer 1

.06x + .04($7,900 - x) = $368

.06x + $316 - .04x = $368

.02x = $52

x = $2,600

$2,600 invested at 6% interest

$5,300 invested at 4% interest
