Dear student,

Given: Saving is directly proportional to amount she earns⇒S=KI    
(1)         
[where S is saving , K is proportionality constant and I is income she earns]⇒K=SI⇒K=25100=14⇒K=14If she earns 3,880 in 1 year then, from (1)⇒S=14×3,880  ⇒S=970Thus, the amount she saves for the college is 970
