Tacon has a gift card for $85 that loses $4 for each 30-day period it is not used. He has another girt card for $75 that loses $3.50 each 30-day period it is not used. If x is the number of 30-day periods, then the equations ( ) can be used to find the number of 30-day periods until the values of gift cards will be equal

30 x 4 = 120

30 x 3.5 = 105
