Monthly Living Expense = 2375
Monthly Fixed Expense = 1975
Step-by-step explanation:
Let monthly living expense be "x"
and monthly fixed expense be "y"
<u>"monthly living expenses were 400 more than his monthly fixed expenses":</u>
x = 400 + y
<u>"Richard total monthly expenses were 4350":</u>
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
