Josh weight 66 pounds and Ben weighs 78 pounds.
Using x to represent Josh's weight, the formula is
x + (x + 12) = 144. Combine like terms to make 2x + 12 = 144. Subtract 12 from each side so that 2x = 132. Finally, divide both sides by 2 to get x = 66, which is Josh's weight. Add 12 pounds to find Ben's weight, which is 78 lbs.
Let x be the price after the discunt on the make and model of the board but before the member discount. Then,
(100 - 5)/100 x = 315.32
0.95x = 315.32
x = 315.32/0.95 = $331.92
Let y be the original price of the board, then
(100 - 15)/100 y = 331.92
0.85y = 331.92
y = 331.92/0.85 = 390.49
Therefore, the original price of the board is $390.49
