witch method is being used, subtraction or elimination? M=MP3 H=headphones 5x’s the cost of mp3 players + 8x’s the total of a set of headphones that = $840 5m+8h=840 3x’s the total cost of an mp3 + 4x’s the cost of a set of headphones =$480 3m+4h= 480 Equations 5m+8h=840 5m=840-8h M=(1/5)*(840-8h) 3m+4h=480 3*(1/5)*(840-8h) +4h=480 3*(840-8h)+20h=2400 2520-24h+20h=2400 -4h=-120 H=30 M=(1/5)*(840-8h) M=(1/5) *(840-8*(30)) M=(1/5)*(840-240) M=(1/5)*(600) M=120
