After t hours, a weather balloon's height, measured in kilometres above the ground, is given by the formula s(t)=8t-t. Determine the velocity of the balloon at 3 hours.

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
