Question 13223
Let x= amount of his savings


There may be two ways to interpret this:  Were his saving increased BY 4 times his savings?  I think that must mean that he ADDS 4x to his present savings of x.  


The equation is 
x + 4x = 25000
5x = 25000
x= $5000


Check:  If his savings of $5000 are INCREASED BY 4 times this amount (which by the way is $20,000), then the result is $25,000.  I'm almost sure this is the way the problem is intended to be interpreted.
