To find out how much money Dragon will earn from the lawn mowing and weeding jobs, we can use the given formula:
\[ E = 25L + 20W \]
where:
- \(E\) is the total earnings,
- \(L\) is the number of lawn mowing jobs,
- \(W\) is the number of weeding jobs.
According to your information, \(L = 4\) (lawn mowing jobs) and \(W = 6\) (weeding jobs).
Now we can plug these values into the formula:
\[ E = 25(4) + 20(6) \]
Calculating each term:
- \(25(4) = 100\)
- \(20(6) = 120\)
Now, add these two amounts together:
\[ E = 100 + 120 = 220 \]
So, Dragon will earn $220 for 4 lawn mowing jobs and 6 weeding jobs.
