Answer:
1.
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!
