Answer:
4 mo.
Step-by-step explanation:
I = PRT P = 600 R = .0375 I = 7.50
7.50 = 600(.0375)T
7.5 = 22.5T
T = 7.5/22.5 = 1/3 yr = 4 mo.

an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7

Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).
Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.
Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.
Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
