$2.00 more.
gathered info from question:
Kai paid $45
Cole paid $24
It is $6 for each pack of pens
So I did 24- 6 (pack of pens) = 18 (what he used for calculators) and then did 18/2 because he bought two calculators. He paid 9 dollars for each calculator
Kai bought two packs of pens = 12 dollars. 45-12=33, how much he used for the calculators. He bought three calculators so I did 33/3=11. He used 11 dollars for each calculator.
11-9=2.
Kai paid $2.00 more than Cole.
Please mark be brainliest :)
