Question

Sam invests $4300 in two different accounts. The first account paid 2 %, the second account paid 13 % in interest. At the end of the first year he had earned $273 in interest. How much was in each account?

Answer 1

2600 AND 1700

Explanation:

both accounts rep by A and B

a + b = 4300

0.02a + 0.13b = 273

a = 4300 - b

0.02(4300 - b) + 0.13b = 273

86 - 0.02b + 0.13b = 273

-0.11b = -187

b = 1700

a = 4300 - 1700

a = 2600
