Question

Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book?

Answer 1

Answer 2

Answer 3

ok... so as I understand it... given I'm in Australia... sales tax is paid on the price...

so you would need to find the normal price without sales tax...

does that make sense..?

Answer 4

yea kinda

Answer 5

sorry I just re-read it... ignore what I just typed...

Answer 6

oka lol is fine

Answer 7

so to get the discounted price you can either

1. find 15% of $24.50 and then subtract it from the price

2. given the price is 100% and you get a 15% discount, meaning you only pay 85%

so Discounted Price = 24.50 x 85/100

does that make sense..?

Answer 8

yeaa

Answer 9

so reading the question... they both have a good method for the discounted price...

now sales tax

you can find 10% of the discounted price and add it to the discounted price... is that ok..?

Answer 10

but you can also think the discounted price is now 100% and so a 10% sales tax means you pay 110%... so find 110% of the discounted price...

so both are valid methods...

Answer 11

so now percentages the simple way

Price = $24.50 10% discount is $2.45 what would 5% discount be..?

Answer 12

$1.25 @campbell_st

Answer 13

?

Answer 14

well close

is 10% = $2.45

5% = 2.45/2

Answer 15

so from there you can find 15% and see what you save and the new price

Answer 16

Not sure about dan but Tess has enough. Basically regular price is $24.50
Tax would be the $24.50 x .10 = $2.45 (or simply just move the decimal over left one to figure it out quicker)
Then $24.50 x .15 to find the total discount OR $24.50 x .85 to find the new discounted price. then add the tax previously calculated and BAM! Good luck

Answer 17

finding 10% just means you move the decimal point 1 place to the left

Answer 18

Now can someone help me with my question I just posted!!!? :]

Answer 19

so what do you think the discounted price will be..?

Answer 20

it wil be 3.25/2

Answer 21

well if 10% = $2.45
5% = $1.23
-----------------
15% = $3.68 this is the discount



Discounted Price = 24.50 - 3.68

so what is the discounted price.?
