Odpowiedź:
[tex]a+\frac{p}{100} *a[/tex]
a)p=32% a=75
[tex]75+\frac{32}{100} *75=75+8*3=75+24=99[/tex]
b)p=24% a=60
[tex]60+\frac{24}{100} *60=60+\frac{72}{5} =60+14,4=74,4[/tex]
c)p=3,5% a=400
[tex]400+\frac{3,5}{100} *400=400+3,5*4=400+14=414[/tex]
d)p=48% a=6 1/4
[tex]6\frac{1}{4} +\frac{48}{100} *6\frac{1}{4} =6\frac{1}{4} +\frac{12}{25} *\frac{25}{4} =6\frac{1}{4} +3=9\frac{1}{4}[/tex]
