Question

While preparing his budget sheet richard Smith noticed that his annual expenses were 18800 while his monthly living expenses were 400 more than his monthly fixed expenses if Richard total monthly expenses were 4350 find his monthly fixed expenses and his monthly living expenses

Answer 1

Monthly Living Expense = 2375

Monthly Fixed Expense = 1975

Explanation:

Let monthly living expense be "x"

and monthly fixed expense be "y"

"monthly living expenses were 400 more than his monthly fixed expenses":

x = 400 + y

"Richard total monthly expenses were 4350":

x + y = 4350

Putting Equation 1 in Equation 2:

(400 + y) + y = 4350

400 + 2y = 4350

2y = 3950

y = 1975

Now, x = 400 + y = 400 + 1975 = 2375
