Kayla and Theresa went to buy some chocolate bars and soda cans. Theresa bought twice the number of chocolate bars and soda cans Kayla bought. If Theresa bought 12 chocolate bars and 18 soda cans, how many chocolate bars and soda cans did Kayla buy in total?
Kayla bought 12 chocolate bars / 2 = <<12/2=6>>6 chocolate bars.
She also bought 18 soda cans / 2 = <<18/2=9>>9 soda cans.
The total number of chocolate bars and soda cans Kayla bought is 6 chocolate bars + 9 soda cans = <<6+9=15>>15 items
