Answer:
The maximum is 3350$
Step-by-step explanation:
As carpenter he earns 35$ per hours
As web design he earns 75$ per hours.
We know that 75>35, so for maximum earning he need to work as web designer more.
He wants to vork as a carpenter at least 10h in week and he worls 50h per week. So for a maximum he works as web designer 50-10=40 hours.
So c=10 and w=40
The equation is:
35c+75w=35*10+75*40=350+3000=3350$
