Use the geometric series formula:
S_n = [a_1(1 - r^(n)]/(1 - r)
Let a_1 = 3
Let n = 8
Let r = 1/2
S_8 = [3(1 - (1/2)^8]/[(1 - (1/2)]
Simplify the right side using your calculator to find S_8, which is the sum of the first 8 terms.
Answer:
8696.10
Step-by-step explanation:
If a car depreciates by 7% each year, this means that 7% of its value that year is subtracted from its previous value. In other words, you can multiply its value by (1-0.07)=0.93.

a) 15cm^3
b) 8:16 am
1 liter = 1,000 cm cubic
Area A = 800
in 10 minutes
12 litters=12,000cm
12,000/800=15 cm
Tank A=15 cm ^3
Area B = 2,000
In 1 minute 5 liters = 5,000 cm^3
5,000/2000 = 2.5 cm^3 in 1 minute
To know how many minutes to reach 15:
15/2.5 = 6
6 minutes (from 8:10 am to 8:16 am)
5liters x 6 minutes =30 liters = 30,000 cm^3
30,000/2000 = 15 cm^3
