Marlene studied 10 minutes more than 4 times as long as Brianna. What expression can you write to represent the situation. What does the variable represent

To figure out what expression we can write to represent the situation, we need to turn the word problem into mathematical functions.

The word "more" means we are adding. The word "times" means we are multiplying.

So the expression should be 4x+10 where x represents the minutes Brianna spent studied.
