Final answer:
After the 10% depreciation, the new value of Robin's computer is $1,125, which is calculated by subtracting 10% of the original price ($1,250) from the original price itself.
Step-by-step explanation:
The question is asking for the new value of a computer after it depreciates by 10%. Depreciation is the decrease in the value of an asset over time. In this case, Robin bought the computer for $1,250. To calculate the depreciation value, we take 10% of $1,250, which is $125. We then subtract this amount from the original price of the computer to find the new value after depreciation.
Original price of the computer = $1,250
Percentage depreciation = 10%
Amount of depreciation = $1,250 × (10/100) = $125
New value after depreciation = $1,250 - $125 = $1,125
The new value of the computer after a 10% depreciation is $1,125, so the correct answer is option 1) $1,125.
