The 32 lb. bag
because the 1 lb of the 32 lb bag costs $1.4
and 1 lb of the 15 lb bag cost $1.7
127/2.54 = 50 inches which equals 4.16 ft
All i know is that the equation of a straight line is y=mx+c .......where m= gradient and c= the y intercept
Well If you tell me what you're solving for I can probably help
