**NO CALCULATOR**

Sydney loves to draw so much that she’s run out of space on her sketchbook, her desk, and even her arms (she’s currently rocking a tiger-striped left arm and a galaxy-themed right leg). To fuel her artistic obsession, she’s buying more markers.

At the store, Sydney sees two options:

Option A: 121 markers for $15.73

Unit Rate (cost per marker): $ 0.13

Option B: $1.98 for 18 markers.

Unit Rate (cost per marker) : $ 0.11

Sydney needs to pick the better buy so she has enough markers to draw a mural on her bedroom wall and maybe one more galaxy on her other leg.

Which pack should Sydney choose to get the better deal per marker? A or B?? B
