4.In M, a city of 50,000 people, MP, a realtor, caculated that a family with M's median family income, 28,000 dollars a year, could afford to buy  M's median-priced 77,000 dollars house. This caculation was based on an 11.2 percent mortgage inerest rate and on the realtor's assumption that a family could only afford to pay up to 25 percent of its income for housing.

Which of the following correction of a figure appearing in the passage above, if  it were the only correction that needed to be made, would yield a new calculation showing that even incomes below the median family income would enable families in M to afford M's median-price house

A. M's total population was 45,000 people

B. M's median annual family income was 27,000

C.M's median-pirce house cost 80,000

D.The rate at which people in M had to pay mortgage interest was only 10 percent

E.Families in M could only afford to pay up to 22 percent of their annual income for housing.

这题为什么选C 而不选D。是不是买房只考虑贷款利率， 而不考虑收入。

It is D, not C. You might have got the wrong "correct answer"

新问，

一直都对mortage interest rate 有疑惑。

是不是，house price*mortage rate=income*25% 这个公式正确吗？
