Anon25 [30]

Answer:

6%: $1776
12%: $7353

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%.
