Answer 1

Answer:

$44.31

Step-by-step explanation:

5.5/100 = x/42 (5.5% is what of 42) (%/100=is/of)

(5.5)(42) / 100 = $2.31(tax) (cross multiply)

42 + 2.31 = $44.31

Answer 2

Answer:

• See below

Step-by-step explanation:

1A

• $42 + 5 1/2% = $42 + $42*5.5/100 = $42 + $2.31 = $44.31

1B

• $15 + 20% = $15 + $15*20/100 = $15 + $3 = $18

1C

• $42 + 6% + 20% = $42 + $42*26/100 = $42 + $10.92 = $52.92
