Answer:
24.2 years
Step-by-step explanation:
The basic formula is I = P * i * t, where I is interest, P is total principal (or profit), i is rate of interest per year, and t is total time in years. I = P * i * t can be rearranged to solve for t: t = I / (i * p).
In this question I = $6400, P = $3200 and i = 8.25%, so we plug in those numbers to get t = 6400 / (0.0825 * 3200), which solves to 24.2424 years.
Answer:
3, 12, 27,48, 75, 108, 147
Step-by-step explanation:
12-3 = 9
27-12 = 15 (9+6)
48-27 = 21 (15+6)
75-48 = 27 (21+6)
108-75 = 33 (27+6)
147-108 = 39 (33+6)
