To calculate Jaden's earnings, we can use the equation based on the jobs he does:
Let:
- \( L \) be the number of lawn-mowing jobs.
- \( W \) be the number of pulling-weeds jobs.
Jaden earns $25 for each lawn-mowing job and $20 for each pulling-weeds job.
The total earnings can be represented by the equation:
\[ E = 25L + 20W \]
Now, if Jaden does 4 lawn-mowing jobs (\( L = 4 \)) and 6 pulling-weeds jobs (\( W = 6 \)), we can substitute these values into the equation:
\[ E = 25(4) + 20(6) \]
Calculating each part:
\[ E = 25 \times 4 = 100 \] \[ E = 20 \times 6 = 120 \]
Now, add these two amounts together:
\[ E = 100 + 120 = 220 \]
Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
