[ 1/1 Equation]
Work: Find the solution of equation a+a*8.8%+(a+a*8.8%)*7% = 365.16 .
Question type: Equation
Solution:Original question:
| a | + | a | × | 44 500 | + | ( | a | + | a | × | 44 500 | ) | × | 7 100 | = | 9129 25 |
| Left side of the equation = | 136 125 | a | + | ( | a | + | a | × | 44 500 | ) | × | 7 100 |
136 125 | a | + | ( | a | + | a | × | 44 500 | ) | × | 7 100 | = | 9129 25 |
| Left side of the equation = | 136 125 | a | + | a | × | 7 100 | + | a | × | 44 500 | × | 7 100 |
| = | 136 125 | a | + | a | × | 7 100 | + | a | × | 77 12500 |
| = | 3638 3125 | a |
3638 3125 | a | = | 9129 25 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 9129 25 | ÷ | 3638 3125 |
| = | 9129 25 | × | 3125 3638 |
| = | 537 | × | 125 214 |
We obtained :
| a | = | 67125 214 |
Convert the result to decimal form :
| a | = | 313.668224 |
