Best ResponseYou've already chosen the best response.1since we have to do this subtraction: \[\Large 980  \left( {\frac{4}{{100}} \cdot 980} \right) = 980  39.2 = 940.8\]

Best ResponseYou've already chosen the best response.1since at the end of one year, the value of the computer is decreased by 4% from its starting value. Now the starting value at the first year is $980.00, whereas the starting value at the beginning of the second year is $940.80
