### Answer & Explanation:

Answer: Option D

If a 10% deposit amounting to $110 has been paid toward buying a brand new TV, how much remains to be paid?

### Answer & Explanation:

Answer: Option B

Explanation:

Let's start with what the total price of the TV would be. If 10% is equal to $110 then 100% equals $x. We just have to multiply $110 by 10 to get total amount=$1100. Out of this amount we then need to deduct the amount already paid which was $110 so we have $1100-$110=$990
