Hey there!

$\frac{7*3}{4}$ $=n$

Simplify the $numerator$ (the top part))

$7*3 = 21$

Then, simplify the $denominator$ (the bottom part, let's pretend it is multiplied by a(n) invisible $1$ ))

$4(1) = 4$

Our answer is: $\boxed {n=\frac{21}{4} }$

Good luck on your assignment and enjoy your day!

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.
