↓Steps Explained:↓
Solve for d
0.1d + 0.15d = 8.50
Group the d terms on the left:
(0.1 + 0.15)d = 0.25d
Form modified equation
0.25d = + 8.5
Divide each side by 0.1
| 0.1d | |
| 0.1 |
| = |
| 0.15 |
| 0.1 |
Divide each side of the equation by 0.25
| 0.25d | |
| 0.25 |
| = |
| 8.50 |
| 0.25 |
d = 34
