150 is your correct answer
Answer:
based on the given formula the amount calculated is for the beginning of the year.
substituting 1 you get 4500 which is beginning of the year 1 when you deposited.
based on that logic substituting 7 for beginning of year 7 will be
4500 + 6 * 0.02 * 4500
4500 + 540
5040
option A.
the 2 in the hundreds place is what times the value of the 2 in the tenths place
2 * 100 = 2 * 10^2
2 * .1 = 2 ^ 10^-1
10^3
1000 times
Distance=speed times time
distance/time=speed
distance=30km
time=2.5hr
distance/time=30km/2.5hr=60km/5hr=12km/1hr=12km/hr
her speed is 12km per hour
