Answer:
3/4 would represent the shaded in parts of the circle

I cannot give you an accurate answer seeing as you did not give much detail
You do mass divided by density
0.0239 x 28 = .6692 (this is the amount of tax paid)
shoes + tax = total
$28 + 0.6692 = $28.6692 which rounds to $28.67 (money is always rounded to the hundredths place)
If you rounded it it would be 4.6
