Question

Mei bought a box of markers for b dollars, a shoulder bag that cost twice as much as the box of markers and a pen that cost $6 less than the shoulder bag. Write the cost of the pen in terms of b.

Answer 1

Box of markers = $ B

Shoulder bag =  Twice as much as the box of markers = $ 2B

Pen = Six less than the shoulder bag = $ (2B - 6)

Hence, the cost of pen is $ (2B - 6).
