8% de R$300,00=

100%------300

8%---------x

100.x = 8.300

100x = 2.400

x = 2.400/100

x = 24

5% de R$200,00=

100%-------200

5%----------x

100.x = 5.200

100x = 1.000

x = 1.000/100

x = 10

3% de R$600,00=

100%-------600

3%-----------x

100.x = 3.600

100x = 1.800

x =1.800/100

x = 18

120% de R$3.300,00=

100%--------3.300

120%--------x

100.x = 120.3.300

100x = 396.000

x = 396.000/100

x = 3.960
