Question 924512: A certain solution of salt water is 10% salt and weighs 50 pounds. More salt must be added to produce a solution that is 25% salt. If x represents the pounds of salt to be added, which of the following expressions represents the number of pounds of salt in the 25% solution?

0.10*50 + x = 0.25*(50 + x)
5 + x = 12.5 + 0.25x
0.75x = 7.5
x = 7.5/0.75
x = 10 lbs of pure salt must be added
