Answer:pretty sure its 20
Step-by-step explanation: so i took 7 and multiplied it by 2 because that is how much is sold every day and got 14. then added six to that and got 20. then i wrote this on my paper:
20  18  16  14  12  10  8  
 S    M   T   W   T   F   S  
so by Saturday you should have 8 and that would leave you 6 on sunday after you sell 2. does that make sense?
