Answer:
Step-by-step explanation:
In a geometric sequence, the nth term is
T_n = ar^(n-1)
a = first term
r = common ratio which can be gotten by dividing second term by first term, third term by second term etc
Therefore
a = 16
r = -3.2 ÷ 16
r = -0.2
T_7 = ar^(7-1)
T_7 = ar^6
T_7 = 16[(-0.2)^6]
T_7 = 16(0.000064)
T_7 = 0.001024
Answer: B
Step-by-step explanation:
Let's calculate the total cost per year:
6168 + 3280 + 2190 + 1200 = 12,838.
Four years will cost 12838 x 4 = 51,352
Your family will help you out with 17,600, so you will need to pay:
51352 - 17600 = 33,752
