Mme a ile mabenkeleng. O rekile koko ka R4.20, sesepa sa ho hlatswa ka R9.45 le sephuthelwana sa pasta ka R1.35. O lefile ka R20. Ke bokae motho wa theko eo a mo kgutlisetsang yona?

John has 2 houses with 3 bedrooms each.  Each bedroom has 2 windows each.  There are an additional 4 windows in each house not connected to bedrooms.  How many total windows are there between the houses?
Palo yohle ya direkwa ke R4.2 + R9.45 + R1.35 = R<<4.2+9.45+1.35=15>>15.
Motho wa theko o mo kgutlisetsa R20 - R15 = R<<20-15=5>>5.
#### R5 

Each house has 3*2=<<3*2=6>>6 windows for the bedrooms
So each house has 6+4=<<6+4=10>>10 windows
So the total number of windows is 10*2=<<10*2=20>>20 windows
