Question

Suppose that David Letterman and Paul Shaffer have the same amount of money in their pockets (say $100 each). How much must Dave give to Paul so that Paul will have $10 more than Dave?

Answer 1

$10

Explanation:

Let the amount of money by each be
`x`.

-At
`x` amount, the two have the same amount. For Paul to have $10 than Dave, his total amount has to be
`\$(x+10)`.

-Hence, Dave has to give Paul $10 for Paul to have $10 more than him.
