Answer:
8.2.69 ≤ x ≤ 17.31
11. x-7.31 ≤ 10
12. x≤17.31
Let the amount in the other Piggybank be x.
If positive;
x-7.31 ≤ 10
x ≤ 10+7.31
x ≤ 17.31
If negative
-(x-7.31) ≤ 10
-x+7.31 ≤ 10
-x ≤ 10-7.31
-x ≤ 2.69
Multiply both sides by -1
x ≥ -2.69
The compound inequality representing the amount of money in the other bank is -2.69≤x≤17.31
