Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
The teacher decided to rewards his students with extra recess on report card day if they got good grades. Students normally get 20 minutes for recess. He told the students that every A got them 2 extra minutes of recess. Every B got them one extra minute. Every C got them zero extra minutes, but every D got them 1 less minute. When report cards came out there were 10 As, 12 Bs, 14Cs, and 5Ds. In total, how much recess would the students get that day?

### Response:
 Wanafunzi wana dakika 20 kuanza.
Wanapata dakika 20 zaidi kwa As kwa sababu 10 mara 2 ni sawa na <<10*2=20>>20
Wanapata dakika 12 zaidi kwa Bs kwa sababu 12 mara 1 ni sawa na <<12*1=12>>12
Hawapati dakika zaidi au kupunguzwa kwa Cs kwa sababu 14 mara 0 ni sawa na 0.
Wanapata dakika 5 zinapunguzwa kwa Ds kwa sababu 5 mara 1 ni sawa na <<-5*1=-5>>-5
Jumla, wanapata dakika 47 za mapumziko kwa sababu 20 plus 20 plus 12 minus 5 ni sawa na <<20+20+12-5=47>>47.
