To find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we can use the formula:
\[ E = 25l + 20w \]
where \( E \) is the total earnings, \( l \) is the number of lawn-mowing jobs, and \( w \) is the number of pulling-weeds jobs.
Given:
- \( l = 4 \)
- \( w = 6 \)
We can substitute these values into the formula:
\[ E = 25(4) + 20(6) \]
Now we calculate each part:
\[ E = 100 + 120 \]
So,
\[ E = 220 \]
Thus, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
