each month maria earns $225 plus $5 for each newspaper subscription she sells. which equation can be used to best determine x, the number of subsciptions maria must sell, if she wants to earn at least $400 next month? need help ASAP

Answer 1

Use this equation:
d=5x+225
To make $400, use this
400=5x+225
To solve, subtract 225 from each side.
Leaving you with 175=5x
Then decide by 5
