To find out how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we can use the equation:
\[ Total\ Earnings = 25l + 20w \]
Substituting \( l = 4 \) and \( w = 6 \):
\[ Total\ Earnings = 25(4) + 20(6) \]
Calculating each term:
- \( 25(4) = 100 \)
- \( 20(6) = 120 \)
Now, adding these amounts together:
\[ Total\ Earnings = 100 + 120 = 220 \]
Thus, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
