Susie bought six pens at the office supply store and paid $4.14. Larry bought a dozen of the same pens at the same store and paid $8.28.

Scott went to this store and bought pens. He paid a total of $5.52. How many pens did he buy?

Respuesta :

he got 4 pens or something. 
Scott bought 8 pens because each pen cost $0.69. So if you multiply $0.69 by 8, it equals $5.52.
