Suppose, number of sunshine days in Boston, Massachusetts is: x
Then, number of sunshine days in Colorado Spring, Colorado will be: 1.4 x
Given that, total number of days of sunshine for both city is: 475
That is, x+1.4x = 475
Solving for x,
x=198
1.4x= 277
Therefore,
Number of sunshine days in Boston, Massachusetts is 198
and
Number of sunshine days in Colorado Spring, Colorado is 277
