Georgia [21]
There are a number of ways you can write the piecewise function. Here is one of them:

p(t)=\left\{\begin{array}{rcl}7t&\mbox{for}&t\leq40\\10.5t-140&\mbox{for}&t>40\end{array}\right.

It could also be something like
p(t) = 7t + 3.50×max(0, t-40)
where the max(x,y) function returns the larger of x or y.

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.
