Question

Concert Merchandise Martha takes her niece and nephew to a concert.

Answer 1

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.
