Vaselesa [24]

Answer:

see explanation

Step-by-step explanation:

Supplementary angles sum to 180° , then

x + y = 180 , that is

$\frac{1}{3}$ y + y = 180 ( multiply through by 3 to clear the fraction )

y + 3y = 540

4y = 540 ( divide both sides by 4 )

y = 135°

Assuming they round to the nearest minute, 322 minutes per month or more for the second plan to be preferable.
