Answer:
The sign would be positive. 
The answer would be 144.
Step-by-step explanation:
Note that there are two negative numbers and two positive numbers: 
positive x positive = positive answer.
negative x negative = positive answer.
Solve: 
(-4) * (-3) = 12
2 * 6 = 12
12 * 12 = 144
144 would be your answer.

The balance is $145 but after one makes he minimum payment of $20, there is $125 left to pay. However interest is added before the next month’s bill is generated.
Remember that percent means out of 100. 1.5% means 1.5/100 = .015
To find 1.5% of 125 we multiply (.015)(125) = 1.875 But as this is money the interest is rounded to two decimal places and so is $1.88
We add this to 125 to get next month’s balance which is 125 + 1.88 = $126.88
