Verified Answer :

First write the relationship in words: "What number is 35% of 400?" 

Then write an equation to represent this relationship: \(x = 35\% \times 400\) or, written another way \(x = 0.35\times400\)

And then solve:
\(x=0.35\times400=140\)

Then answer the question: "Adam has saved $140."
