Your answer is C. C=7.50n+ 570
there are 4 1/4 per a whole
so multiply 0.75 x 4
0.75 x 4 = 3.00 dollars per pound
1.)
Velocity is in m/s, and acceleration is in m/s^2 like you said. Because of this, we can calculate this by dividing the speed by the time it took to get to that speed.
(20 meters/second) / 10 seconds = 2 meters/ second^2
2.)
Same thing with the first one.
(100 meters/second) / 4 seconds = 25 meters / seconds^2
