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

Leokris [45]

Mr zambito buys a 3 1/2 - pound bag of dog food every 3 weeks mr zambito feeds his dog the same amount of dog food each day how
Murljashka [212]
3 1/2 pound = 7/2 pounds.
We know that the dog eats 7/2 (3.5) pounds every 21 days since there are 7 days in a week and Mr.Z only buys dog food every 3 weeks.

Set up a proportion.     <u>3.5 lb</u>     =    <u>    x     </u><u>
</u>                                  21 days         365 days
<u>
</u>Cross multiply and divide. 3.5 lb x 365 days = 1277.5 / 21 days = 60.83 lb
<u>
</u>
