500 + 50x = 75x

Now subtract 50x from 75x.
500 = 25x

Then divide 500 by 25.
20 = x

They would've saved the same amount($2,000) on the 20th week.

zhuklara [117]

Answer:

$\boxed {cot T = -\frac{5}{12}}$

Step-by-step explanation:

x² = 13² - 12²
x² = 169 - 144
x = √25
x = 5

<u>Taking the cot value</u> :

cot T = adjacent / opposite
cot T = -5/12 (As cot is negative in Quadrant 2)
