Evidence for the work

Mark's annual income is 45000$

=> Mark's net monthly pay: M  = 45000/12 = 3750$

2.

The percentage of each expenditure per month:

Rent: (850/3750) x 100 = 23%

Food: (300/3750) x 100 = 8%

Car insurance and gas: (190/3750) x 100 = 5%

Entertainment: (760/3750) x 100 = 20%

Clothes: (150/3750) x 100 = 4%

3.

Mark's top monthly expenditure includes renting(23%) and entertainment (20%).

He should cut costs to these to be able to save more money each month.

Hope this helps!

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
