Initially, she had $400
Every month, this amount decreases by the amount she spends, which is $35
So, the amount she has used after 'm' months is: 35 * m
The amount left after 'm' months
= Initial - Money used
= 400 - 35*m
So,
D = 400 - 35m
Every month, this amount decreases by the amount she spends, which is $35
So, the amount she has used after 'm' months is: 35 * m
The amount left after 'm' months
= Initial - Money used
= 400 - 35*m
So,
D = 400 - 35m
