jimthompson5910 (jim_thompson5910):

what is 10% of $12.50 ?

OpenStudy (anonymous):

1.25

jimthompson5910 (jim_thompson5910):

subtract that from the price of the strategy book

jimthompson5910 (jim_thompson5910):

$12.50 - $1.25 = ???

OpenStudy (anonymous):

11.25

jimthompson5910 (jim_thompson5910):

That's the sale price of the strategy book

jimthompson5910 (jim_thompson5910):

Add that to the price of the video game

OpenStudy (anonymous):

ok

jimthompson5910 (jim_thompson5910):

Once you get that total, tell me what you get

OpenStudy (anonymous):

49.95+11.25=61.2

jimthompson5910 (jim_thompson5910):

good

jimthompson5910 (jim_thompson5910):

now we need to add on the sales tax

jimthompson5910 (jim_thompson5910):

what is 6.5% of $61.20 ?

OpenStudy (anonymous):

3.978

jimthompson5910 (jim_thompson5910):

round that to the nearest penny to get $3.98

jimthompson5910 (jim_thompson5910):

Add this onto the previous total $61.20 + $3.98 = $65.18

jimthompson5910 (jim_thompson5910):

So the final and total price for everything (after the discount and taxes are applied) is $65.18
