Răspuns :
a) 250- 30/100*250 = 250 -3*25 = 250-75 = 175
b) 250 + 40/100 * 250 = 250 + 4*25 = 250+100=350
c) Dupa prima reducere: 250 - 10/100*250 = 250 - 25 = 225
Dupa a doua reducere: 225 - 20/100 * 225 = 225 -2*225/10 = 225 - 450/10 = 225 - 45 = 180
b) 250 + 40/100 * 250 = 250 + 4*25 = 250+100=350
c) Dupa prima reducere: 250 - 10/100*250 = 250 - 25 = 225
Dupa a doua reducere: 225 - 20/100 * 225 = 225 -2*225/10 = 225 - 450/10 = 225 - 45 = 180
