Each T shirt costs $21.

Since Martha takes her niece and nephew to a concert, and she buys T-shirts and bumper stickers for them, and the bumper stickers cost $ 1 each, and Martha's niece wants 1 shirt and 4 bumper stickers, and her nephew wants 2 shirts but no bumper stickers, to determine, if Martha's total is $ 67, what is the cost of one shirt, the following calculation must be performed, posing linear equations:

  • 1 bumper sticker = $ 1
  • 1 T shirt + 4 bumper stickers + 2 T shirts = $ 67
  • 1X + 4 x 1 + 2X = 67
  • 3X = 67 - 4
  • X = 63/3
  • X = 21

Therefore, each T shirt costs $21.
