Based on the calculations, the sum of this geometric series is equal to 9,990.
<h3>The standard form of a geometric series.</h3>
Mathematically, the standard form of a geometric series can be represented by the following expression:

Where:
- a₁ is the first term of a geometric series.
<h3>How to calculate the sum of a geometric series?</h3>
Also, the sum of a geometric series is given by this mathematical expression:

<u>Given the following data:</u>
- Common ratio, r = 900/9000 = 0.1
Substituting the given parameters into the formula, we have;

S = 9000(0.999)/0.9
S = 8,991/0.9
S = 9,990.

Answer:
K1310.4
Step-by-step explanation:
Basic pay per hour = K7.20
Overtime pay during the week per hour = 1 1/2 * K7. 20 = K10.8
Weekends = 2 * K7.20 = K14.4
Basic hours per week = 70 hours
In a fortnight :
Basic hours = 70 * 2 = 140 hours :
Hence, Overtime during the week = (160 - 140) = 20 hours
Weekend hours = (4 +2) = 6 hours
Total earning :
(140 * 7.20) + (20 * 10.8) + (6 * 14.4)
1008 + 216 + 86.4
= K1310.4
That would be (2)(18 cups) / (4 hours), or 9 cups per hour.
