100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.
It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.
The answer should be D.
y= 720x +100
Answer:
x=0
Step-by-step explanation:
7x+(-7)=9x-7
Add 7 to each side
7x+(-7)7=9x-7+7
7x = 9x
Subtract 7x from each side
7x-7x = 9x-7x
0 = 2x
Divide by 2
0 = 2x/2
0 = x
