Afarmer can pick 12 boxes of apples per day.

at that rate, how many boxes can the farmer pick in 45 days?

57

450

540

600

It's 540 cause in one day he picks 12 so in 45=540 cause 45×12 that's all

The answer would be 540 this is my proof 

  45
 x12 
 
   90
+450

  540 that is your answer  

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000

I’m pretty sure the * means multiplication. so, if you multiply 5*1, it would equal 5. they are basically are-writing 5x1 as 5*1. so they would be… 5 10152025303540455055
