Final answer:
To find the depreciated value of Robin's computer after one year, subtract 10% of the original value from the original value. The value of Robin's computer after one year would be $1,125.
Step-by-step explanation:
To find the depreciated value of Robin's computer after one year, we need to subtract 10% of the original value from the original value.
Step 1: Calculate the amount of the depreciation = 10% of $1,250 = $125
Step 2: Subtract the depreciation from the original value to find the depreciated value = $1,250 - $125 = $1,125
Therefore, the value of Robin's computer after one year would be $1,125.
