A truck is bought at the price of $67,000. The price decreases at the rate of .30 every year (t). Which equation matches this ex
ponential model?A) f(t) = 67(.70)tB) f(t) = 70(67,000)tC) f(t) = t(.70)67,000D) f(t) = 67,000(.70)t
1 answer:
Data:
Initial price: $67.000
Price decrease: .30 each year t
The general form of a model of exponential decrease is:

Where P0 is the initial price, r is the rate of decrease and t the number of periods.
Then, for the given situation you get the next equation:

Then, the answer is the option D.

180/27 frames = 6.66667 or 6 2/3 minutes.
3.5 times as much flour as chocolate chips....
f = 3.5c
f = 1 3/4 (or 1.75)
1.75 = 3.5c
1.75 / 3.5 = c
0.5 = c......chocolate chips needed would be 1/2 a cup
