Marvin’s situation can be used to solve the equation 18 x 4 1/3 = x
Since the equation uses multiplication, you have to look for the situation that uses multiplication as well.
The baker’s situation uses subtraction, so it’s out of the question.
Mason’s situation uses division, so it’s out of the question as well.
Lastly, Rachel’s situation uses addition, so it’s out of the question.
This leaves Marvin’s situation as the correct answer.
