Answer:
16) 6%
17) 4 years
18) 2 years
Step-by-step explanation:
The formula for these questions is I = PRT
16) 27 = 900 (R) (0.5)
Notice how I used 0.5 instead of 6 for the T. T has to be measured in years, not months and 6 months is half a year.
R = 0.06 = 6 %
17) 480 = 2000 (0.06) (T)
T = 4 years
18) 1080 = 4500 (0.12) (T)
T = 2 years
