Melissa wants to buy a new pair of shoes that have an original price of $45. Melissa has a coupon for 20 percent off to use on them, which amounts to a discount of $9. If sales tax is 9 percent on the final price of the shoes, how much tax will she need to pay? $3.24
$4.05
$4.86
$4.95

$3.24

Step-by-step explanation:

First, we subtract the $9 from the $45, so that equals $36

9% of the 36% is added to the final price as tax

36 x 0.09 = 3.24

45-9=36

what we could do is first find out how much 1% is, 36÷1=0.36.

so 0.34×9=3.24

the final answer is 3.24

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
