Question

Sedric Angell invested an amount of money in Amoxil stock that earned an annual 10% return, and then he invested twice the amount in IBM stock that earned an annual 12% return. If his total return from both investments was $2,890, find how much he invested in each stick.

Answer 1

Let X = amount of money invested in Amoxil stock.

2X = amount of money invested in IBM stock.

.10X + .!2(2X) = 2890

.!0X + .24X = 2890

.34X = 2890

X = 8500

2X = 17000

$8500 was invested in Amoxil stock and $17,000 was invested IBM stock.
