2. The NGO used 90% of the donation to buy a machine from Japan. Calculate the cost of the machine to the nearest Japanese Yen.  

Answer 1

1. 1dollar=Ksh 102.40
   200000dollars =?
   200000dollars   × Ksh102.40
         1dollar
   = Ksh 20,480,000
2. 100 Jap yen= Ksh 93.30
        ?           = 0.9(20,480,000)
                      =0.9(20480000) × 100yen
                               93.3
                      =19755627.01
                      ≈19,755,627
