Answer:
The answer is letter c.
Explanation:
In order to know the answer, it is best to check what is given in the scenario above.
45 minutes = the time it takes for Betty and Dyan to pick 8 quarts of strawberries.
45x minutes= this refers to the time it takes for Dyan to pick 8 quarts of strawberries
In the rational expression, 45x-10, we've already known that 45x refers to minutes or the time it takes for Dyan to pick 8 quarts of strawberries, thus 10 here refers to minutes or time as well.
The mathematical operation used is "subtraction," so this means that Betty takes a shorter time than Dyan when it comes to picking strawberries in the situation above.
Thus, the denominator represents the time it takes Betty to pick 8 quarts of strawberries if she takes 10 fewer minutes than Dyan.
