Anna started with $10. She saved an additional $5 each week. Write an equation that can be used to determine the total amount saved in dollars, t, after a given number of weeks, w. Determine which variable is independent and which is dependent. Then, graph the total amount saved for the first 8 weeks.

Explanation:

Okay so, Anna starts with $10, right? So this means the y-intercept is $10 and we can start with

y = mx +10

Then it says she gets $5 a week which is the m in the equation so you get

y = 5x +10

The x will stand for the number of weeks.

The independent variable is the number of weeks because it is affected by nothing.

The dependent variable is the amount of money she receives weekly because it is being measured against the x variable.

Sorry, I cannot graph this for you, but remember that the slope is 5 and you graph rise over run

I hope I helped and good luck with homework!

What we know:

She started with 10$ and +5$ a week

t, is the saved in w, weeks

Answer:

t =10 + 5w

As for the graph i cant do but just switch the w, with an 8 like so

t=10 +5(8)

then turn that to a graph

Sorry, That's the most i can do,
