The owner of a sailboat reduced the price of the boat by an equal amount each month because there were no interested buyers. After 8 months, and a $960 total reduction in price, the boat sold.
By how much was the price of the boat reduced each month? Use a signed number.
Correct Answer
-$120
Explanation
The total reduction expressed as a signed number is \(-\$960\). Dividing equally over 8 months:
\[ -960 \div 8 = -120 \]
Unlike signs → negative. The price was reduced by $120 each month. Check: \(-120 \times 8 = -960\) ✓
