Answer:

Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as

PRT+PRT=Total Interest
0.03x+0.11(2x)=104.5
0.25x=104.5
x=418
x+2x, 418+2(418)=1254
Total Investment=1254 dollars
