Answer:
3n + 2
Step-by-step explanation:
Well this is easyyy:) you just need to multiply 4 and 2/7 by 1/2
buttt before we set up our question lets get 4 and 2/7 as an improper fraction
2
4 ----
7
we do that by multipying the 4 and 7 and then adding 2 soo lets do that
4 x 7 = 28
28 + 2 = 30
look we have our numerator!! (the top number)
and we dont have to do anything to the numerator just keep it the same as 7 :) lets look at our new improper fraction
30
------
7
see now we can set up our problem:)
30 1
------ x -----
<span> 7 2
</span>now all we do is multiply across:)
30 1 = 30 x 1 = 30
------ x -----
<span> 7 2 = 7 x 2 = 14
</span>here is our new fraction
30
------
14
wait lets simplify it by dividing each number by 2
30 ÷ 2 = 15
------
<span> 14 </span>÷ 2 = 7
ahh this is better here is our simpified fraction
15
-------
7
or as a decimal it is 2.142857143
either one is the correct answer:)

then multiply it by the item cost.
Therefore, </span><span>63.20 x .045 = $2.84</span>
