Answer:
y=0,y=7/5,y=-9/4
Step-by-step explanation:
12y(5y-7)(4y+9)=0
Using the zero product property
12y =0 (5y-7) =0 (4y+9)=0
12y/12 =0/12 5y-7 +7 =0+7 4y+9-9=0-9
y =0 5y = 7 4y = -9
5y/5 = 7/5 4y/4 =-9/4
y = 7/5 y =-9/4
Her expenses are a fixed expense of $4500 and a weekly expense of $200.
Let's call the unknown number of weeks w.
In w weeks, the weekly expenses will by 200w.
The total expense is
200w + 4500
In a week, when earns $550. In w weeks, she earns 550w.
Set the expenses equal to the earnings and solve for w.
550w = 200w + 4500
Subtract 200w from both sides.
350w = 4500
w = 12.86
It takes her 12.86 weeks to break even.
If she works 13 weeks, she begins to make a profit.
