Question

Can someone please help me answer number 6!?! please!!

Answer 1

Hello there! Your answers would be:

a. 600 - 75x = y

b. 8 months

Need an Explanation?:

Part a:

Okay, so she has 600 dollars, and she has a monthly bill, but no income. This means she is not earning any money, only loosing some.

This equation will model your situation: 600 - 75x = y

This is because:

• The 600 remains constant, you are taking away from it. The 75 x represents the amount from the total taken away after each month.
• Again, she does not earn money, only spends it on her bill.
• Y represents the total amount of money she has left after each month.

Part b:

This is asking us to see how many months it'll take for her to have $0. The question is telling us to have g(x) = 0. (This is just another way of saying y = 0, which translates to her having no money left)

So, plug 0 into the equation in place of y and solve for x.

600 - 75x = 0

Start by subtracting 600 from both sides to work to isolate x.

-75x = -600

Next, divide -600 by -75 to finish isolating x and get your answer.

X = 8

This means it will be 8 months before her checking account reaches 0.

So, these are your final answers. I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question!
