$=\frac{2}{5}$

$\textsf{Money spent on bills :}$

$=\frac{1}{10}$

¤ To find:

$\textsf{Mrs.Stefan total monthly expenses}$

¤ Taken:

To find velocity:

$V=\frac{D}{T}$

Where,

V = Velocity

D = Displacement

T = Time

To find acceleration:

$A=\frac{V1-V}{T}$

Where,

A = Acceleration

V1 = Final velocity

V = Initial velocity

T = Time

To find potential energy:

$Pe=mgh$

Where,

Pe = Potential energy

m = Mass

g = Acceleration due to gravity

h = Height
