Answer:

a.) 12.96kg b.) $90

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
