Answer 1

Answer when possible..

Answer 2

There are two ways to solve this question:
regular price is `$18` and the book is on sale `15%` off
if you want to check how much money you will save then you can multiply \[\large\rm regular ~price *\frac{ percent ~ off}{100}\]
convert 15% to decimal by dividing 15/100
\[18* 0.15= $2.70\]
you will save $2.70
`18-2.70=$15.30`
and then you have to pay 6% tax of 15.30
same formula again \[\large\rm price * \frac{percent }{100}\]
`15.30 *0.06=0.918=$0.92` (6/100=0.06)
0.918 =0.92 rounded to two decimal places
you have to pay 0.92 cents tax for %15.30 book
so add 15.30+0.92= `$16.22`
your total will be 16 dollar 22 cents.

2nd way) if you wanna know how much money you will be paying:
1st) subtract the percent off from 100 (100-15=85%)
2nd) divide the difference by 100 85/100= 0.85
3rd) multiply the regular price by 0.85 `0.85*18=$15.30`
4th) when you have to add some percent then you have to add 100+6=106
5) divide 106 by 100 (106/100=1.06)
6)multiply it by the discounted price (15.30*1.06=16.218)
7) round it to two decimal places 16.218=` $16.22 `
same answer:=))
