Answer:
Step-by-step explanation:
Let x represent the amount invested at 6%. Then the amount invested at 12% is 4x+249. Sherrie's interest is ...
   0.06x +0.12(4x +249) = 988.92
   0.54x + 29.88 = 988.92
   0.54x = 959.04
   x = 959.04/0.54 = 1776
   4x+249 = 7353
__
Sherrie invested $1776 at 6% and $7353 at 12%.
