Answer:
After one year, the value of the tent will be worth 100% - 12% = 88% of its original value.
After two years, the value of the tent will be worth 88% - 12% = 77.44% of its original value.
After three years, the value of the tent will be worth 77.44% - 12% = 68.1472% of its original value.
To find out how much the tent will be worth in 3 years, we can use the following formula:
Value after 3 years = original value x (1 - depreciation rate)^number of years
Value after 3 years = $866 x (1 - 0.12)^3 = $518.98
Therefore, the tent will be worth $518.98 in 3 years.
