Answer:
$46.42
Step-by-step explanation:
a=price after discount (without sales tax)
a/55=20/100
100a=55·20
100a/100=1,100/100 (the 1,100 is from the 55·20)
You get 11 and then you have to subtract 11 from 55.
55-11=44, so a=44
Then you multiply 44·0.055 (you get 0.055 because you have to make 5.5% a decimal. You get 2.42.
You add 2.42 and 44 and you get $46.42
