She earns $385 a week
35 x 11= 385
if she spends 300 shes left with 85 dollars
now if we count the 300 dollars in our estimation
385 x 4= 1,540 so she earns a 1,540 a month
1,540 x 12= 18,480
so this means she earns right around $18,480 a year
If we don't include the 300 she would earn
85 x 4= 340 a month
340 x 12= 4,080 a year
i hope this helps XD
