To solve this you need to take the answer from the previous iteration.
Iteration 1: The answer is given
a1 = 300
Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2
a2 = 300/2 = 150
Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50
Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5
Answer: 12.5
Answer:
The original price is $210.
Step-by-step explanation:
p*2/3 -25 = 115
where p is the original price.
p*2/3 = 115 + 25
p*2/3 = 140
p = (140*3)/2 = 210

A. The free term represent the height of the window, on the second floor
B. -16t²-8t+24=-8(2t²+t-3)= - 8(2t+3)(t-1)
C. - 8(2t+3)(t-1)=0
2t+3=0, 2t=-3, t1=-3/2
t-1=0, t2=1
D. t1 (I think) represents the time before the paper ball reached the window, when Jacob only began to threw the the ball,
t2 represent the time when ball passes the window , and the height of the ball was the same as the height of the Jacob hand that was trowing the ball (while he is on the second floor)
