The function f(x) = 4500(0.98)^x represents the value in dollars of a vehicle x years after it has been purchased new. what is the average rate of change in value per year between years 5 and 10? a. −$3676.83/year b. −$0.98/year c. −$78.16/year d. −$4500/year

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
