Respuesta :
The amount that marcus end up paying for the two shirts originally priced at $28.99 and $30.29 is given by: Option A: $39.59
How to find the percentage from the total value?
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we're given that:
Cost of two shirts originally is $28.99 and $30.29
30% is off on each of them, so we get:
New price of each shirt = Old price of each shirt - 30% of old price of each shirt
New price of each shirt = [tex]28.99 - \dfrac{28.99}{100} \times 30[/tex] and [tex]30.29- \dfrac{30.29}{100} \times 30[/tex]
This sums up to $41.496
Now, at this price, there'd be application of 10% additional discount.
That will make the new price as:
[tex]41.496 - \dfrac{41.496}{100} \times 10 =37.3464[/tex]
Now, on this price, there'd be applied 6% sales tax
So, the amount he paid for 2 shirts = discounted price + 6% tax on discounted amount
= [tex]37.3464 + \dfrac{37.3464}{100} \times 6 \approx 39.59 \: \rm dollars[/tex]
Thus, the amount that marcus end up paying for the two shirts originally priced at $28.99 and $30.29 is given by: Option A: $39.59
