Answer:
40 is your correct answer
I think the best answer is 3 to 9 but thats not a answer so 3 to 6
Answer: $48.60
Get this answer by multiplying 48 by 1.08
-18-(-12)=-6
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative.
Hint: when you see two negative sign just turn them into plus sign.
