### Instruction:
 Aria ana mara mbili ya idadi ya mikopo ya shule ya upili kama Emily, ambaye ana mara mbili ya idadi ya mikopo ya shule ya upili kama Spencer. Ikiwa Emily ana mikopo 20, ni mara mbili ya idadi ya jumla ya mikopo ya shule ya upili ya watatu?


### Response:
 Emily ana mikopo 20. Spencer ana 20/2=<<20/2=10>>10 mikopo. Aria ana mikopo 20 x 2 = <<20*2=40>>40. Jumla ya mikopo ya shule ya upili ya watatu ni 20 + 10 + 40 = <<20+10+40=70>>70 mikopo. Mara mbili ya idadi ya jumla ya mikopo ni 2 x 70 = <<2*70=140>>140 mikopo.
