Answer:
Lena's account will reach zero dollars in two months.
Step-by-step explanation:
First, identify what you know:
1) Lena has $1000 in her bank account
2) Every month, she is charged an automatic $500 for her cell phone bill.
How many months will it take for Lena's account reach zero dollars, if that's the only payment she has to make?
1000/500 = 2
Lena can make two payments of $500, before the account reaches zero!
Hope this helps!
