Answer:
Pat
Explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.
