So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation: 
+ x = 
Step 2: Isolate x by subtracting from each side
+ x - = -
Step 3: The numbers on the left cancel out, leaving x alone
x = 
Step 4: Convert the answer to decimals
x = 3.6

Step-by-step explanation:
The given expression describes the GP with
<u>The first term:</u>
- t = 80(1.23²⁻²) = 80(1.23⁰) = 80
<u>The common ratio: </u>
It is required to find the sum of the terms from 2 (the bottom number of sigma) through 29 (the top number of sigma)
The number of terms is
The sum of the first 28 terms is
- Sₙ = t(rⁿ - 1)/(r - 1)
- S₂₈ = 80(1.23²⁸ - 1)/(1.23 - 1) = 114125.75573 ≈ 114126 (rounded)
