Mona is ordering cups for her school.  Company A charges $3.50 for each cup and a one-time starter fee of $14.  Company B charges $0.50 for each trophy and a one-time starter fee of $22.  
Which inequality can be used to find x, the minimum number of cups that can be ordereed so that the total charge at Company A is less than the total charge at Company B?

• 3.5x + 14 < 0.5x + 22
• 3.5x + 14 > 0.5x + 22
• 3.5 + 14x < 0.5 + 22x
• 3.5 + 14x > 0.5 + 22x
