David has b dollars in his bank account; Claire has three times as much money as David. The sum of their money is $240. How much money does Claire have?

David has b
Claire has 3b since three times as much means we multiply b by 3

The sum of their money is found by adding David's bank balance to Claire's bank balance to get the equation:
3b + b = 240

To solve for b, we type this equation into our search engine and we get:
b = 60

So David has 60 dollars in his bank account.

Therefore, Claire has:
3(60) = 180
