The graph shows the function f(x) = 2* What is the value of x when f(x) = 4?

A. 3
B.2
C. 1
D. 0

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer:   he will receive $21093.75 only.

explanation:

since we have given that

cost of house = $180,000

since he has a coinsurance clause of 75%,i.e. he does not fully insured his property.

amount the owner insured for the property = $101,250.

amount he lost in damage = $50,000

amount he will receive from insurance is given by

so, he will receive $21093.75 only.
