Suppose $2000 is invested at 7% interest compounded continuously. How long will it take for the investment to grow to $18,000? Use the model A ( T ) = P e^rt and round to the nearest tenth of a year. It will take approximately years for the investment to grow to $18,000

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.
