<u>Answer:</u>

<h2><u>-2.25</u></h2><h3><u>Step-by-step explanation:</u></h3>

Lets start with D:

It says, 0.43 but we're on the OPPOSITE of 0, so it can't be a positive number.

Same goes for C.

Now we are on to our last two.

B, is -2.5 and A, is -0.8

So, now we look at the point <em>B </em>and <em>assume</em>, because it says Select a reasonable value for Point B.

To me, point <em>B </em>looks to be about around -2.0

So, the <em>reasonable value </em>for this problem would be -2.25

Juliette [100K]

Answer:

34 weeks

Step-by-step explanation:

Hello!

We can set up an equation to solve for the number of weeks.

Let w = the number of weeks he is saving up.

The equation is 315 = 115 + 10w - 140

  • 315 is the target amount
  • 115 is the current amount
  • 10w is the rate of growth
  • 140 is the current debt

<h3>Solve for w</h3>
  • 315 = 115 + 10w - 140
  • 315 = -25 + 10w
  • 340 = 10w
  • 340/10 = w
  • 34 = w

He needs to save up for 34 weeks.
