Plan A = 50 + 0.05(x-500)
Plan b = 20 + 0.06 (x-200)
set A equal to B
50 + 0.05 (x-500) = 20 + 0.06(x-200)
50 + 0.05x - 25 = 20 + 0.06x -12
rearrange like terms on one side.
50 - 25 -20 +12 =0.06x -0.05x
17 = 0.01x
x = 1700 minutes.
(70x10)+(6x1)+(4x1/10)+(2x1/100)+(9x1/1000)
1/2 because he has 16 pieces gives 4/8 which is a half and therefore has a half left
