Answer:
the original price of the book is $20
Step-by-step explanation:
sometimes in a question, they put things in the question that don't actually help us get to the answer. usually we ignore it, but i'm going to list them out just to help you a bit more.
<u>Things that are useless:</u>
- his name is Jarred (his name could be gary, it doesn't affect us getting the answer)
- he went to a bookstore (he could've gone to the library, it wont affect us getting to the answer)
- the book is softcover (it could be any type of book, wont affect us getting to the answer)
- the item is a book (it could be anything that he bought, wont affect us getting to the answer.)
<u>Things that are helpful:</u>
- the book was on sale (helps us know that the price was reduced)
- the book was on sale 10% (helps us know how much it was reduced by)
- he spent $18 for the reduced price (helps us know how much he spent)
Ok, now that we know those, let's work on the question.
let b be the original book price
we need to find 10% so we have to use 90% (because 100 - 10 = 90)
if we needed to find 20% we would use 80% (because 100 - 20 = 80)
and so on.
90% of b = 18 (90% of the og. book price equals 18)
90/100 × b = 18 (write a correct equation and make the percent a fraction)
9/10 × b = 18 (simplify both sides of the equation)
9 × b = 180 (multiply both sides of the equation to get rid of fraction)
b = 20 (divide both sides of the equ. to get b by itself)
the original price of the book is $20
hope this helped :D
good luck my friend

mr. John is shopping for new Apple eyes at a store all lights are on sale for 10% off sales tax is 7% which expression could mr. Jones use to calculate the total cost any wise X fun cost of the item the original price is $100 equal 100 and see what toys will give you the correct price
So the (1+2) could be with the 2 under the fraction or not
PEMDAS
simplify parenthasees first
then mulitplicationthen division
then addition and subtraction
6/2(1+2)
if it is
(6/2)(1+2) then go to AAAAAAAA
if it is 6/(2(1+2)) then go to BBBBBBBBB
AAAAAAAAAA
(6/2)(1+2)
simplify 6/2
2/6=3
also simplify 1+2
1+2=3
(3)(3)=9
BBBBBBBB
6/(2(1+2))
simplify inner parthenasees first
1+2=3
6/(2(3))
multiply with parenthaseess
2(3)=6
6/6=1
theh answer is either 9 or 1 depending on where the parenthasees is
