Por ende, la respuesta correcta es B.
Answer:
(D) 1+0.06m
Step-by-step explanation:
Let's say that m=$120
(A)= $127.2
(B)= $127.2
(C)= $127.2
(D)= $8.2
As you can see after I substituted in 120 for (m) and solved, D is the only equation that did not represent her current balance.
I hope this helps!
