Answer:
Mike spends $160,000 on A and $75,000 on B
Explanation:
Lets call the rental properties as A and B.
A yields 10% anb B yields 12%.
Total investment=$235,000
Expected income=$25,000
Let the amount he invests in A be x.
Then amount spent in B=$(235,000-x)
Income from A=x × 0.1 ----------------(1)
Income from B=(235,000-x)× 0.12 ---------------(2)
Sum of incomes =$25,000
Taking sum of both equations,
x × 0.1 +(235,000-x)× 0.12 =25,000
235,000×0.12 -0.02×x =25,000
28,200 -0.02×x =25,000
0.02×x =3,200
x=[tex]\frac{3,200}{0.02}[/tex]
x =$160,000
