Solve the following equation
0.07c+7<0.03c+19
Solve for c
0.07c + 7 < 0.03c + 19
Group variables
Group our variables 0.07c and 0.03c
subtract 0.03c from both sides
0.07c + 7 - 0.03c < 0.03c + 19 - 0.03c
Cancel 0.03c on the right side:
0.04c + 7 < 19
Divide each side by 0.07
| 0.07c | |
| 0.07 |
| = |
| 7 |
| 0.07 |
Group constants
Group our constants 7 and 19.
subtract 7 from both sides
0.04c + 7 - 7 < 19 - 7
Cancel 7 on the left side:
0.04c < 12
Divide each side of the inequality by 0.04
| 0.04c | |
| 0.04 |
| < |
| 12 |
| 0.04 |
c < 300
Final Answer
c < 300
