Sagot :
You can use the fact that both 20% and 15% discounts will be merged to reduce 35% of the price of the book that Jamie buys.
By buying the book on sale and using the coupon, Jamie will save
Option B: $11.55
How are discounts calculated for the case when its sale and we've got discount coupons too?
Suppose the sale gives p% off.
And the discount coupon provides q% off.
Then we have total discount applied on the cost of the object bought as
(p+q)%
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]
Using the above fact to calculate the amount that Jamie saved
Since the sale offers 20% discount and Jamie has got 15% discount coupon for any fiction book, thus, total 35% will be discounted if Jamie buys fiction book.
Since the price of the fiction book that Jamie brought is $32.99, thus,
Saved amount = 35% of $32.99 = [tex]\dfrac{32.99}{100} \times 35 = 0.3299 \times 35 \approx \$11.55[/tex]
Thus,
By buying the book on sale and using the coupon, Jamie will save
Option B: $11.55
