Question 1111869
john invested some money in a certificate of deposits that earns 5.5% annual simple interest
Amount x at 5.5%
Interest earned = 5.5% x

 and $8,000 more in a municipal bond that earns 6% annual simple interest. 
8000 @ 6%
6%of 8000 = 480
the amount of interest earned in one year was $1630,

Interest I + Interest II = 1630

5.5%x+480= 1630
5.5x + 48000 =163000
5.5x = 163000 - 48000 

5.5x = 115000
x=20909
20909 was invested in the certificate of deposit
