Answer:
C
Step-by-step explanation:
$6500 is a one time purchase so there is no variable attached.
$550 and $900 per week is reoccurring so there will be a variable attached.
Since $900 is what she is making each week, this will be separate from her costs (can eliminate D).
To make a profit, her amount earned will need to be greater than her expenses, so the answer is C.
40+90=130
180-130=50
50+130=180
x=130
50+x=180
If you are asking when you divide ten into a number, remember this, anything that ends with a 0, it is divisible by 10.
