Marlon withdrew $25 from his savings account every week for 5 weeks. Which equation is the best choice to help him determine the total amount of money he withdrew?
Group of answer choices
(25)(−5) = −125; he withdrew $125
(−25)(5) = −125; he withdrew $125
(−25)(−5) = 125; he withdrew $125
(25)(5) = 125; he withdrew $125
The equation that best represents the total amount of money Marlon withdrew is:
