b) $90

Step-by-step explanation:

[tex]a)\ 12+\frac{12\times 8}{100} =12+0.96=12.96[/tex]

[tex]b)\ 75+\frac{75\times 20}{100} =75+15=90[/tex]

Answer:

a.) 12.96kg b.) $90

Step-by-step explanation:

increasing 12 by 8%, first find 8 percent of 12,

8/100 x 12, then add that to the original 8

so 8/100 x 12 = 0.96, so increasing 12kg by 0.96kg, we get 12.96 kg

increasing 75 dollars by 20%, or 1/5th, we find 1/5th of 75, then add it onto 75

1/5th of 75 is 15, so 75 + 15 = 90
