In mathematical form, it would be:

n-8 < 11

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.
