Samuel orders four dvds from an online music store. each dvd costs $9.34. he has a 25% discount code, and sales tax is 7%. round sales tax amounts to the nearest cent. what is the total cost of his order?

$31.02

Step-by-step explanation:

Cost of four DVDs at the rate of $9.34 per one = $9.34 x 4

                                                                              = $37.36

Discount code                                                       = 25% of the cost price

                                                                              = 25% of $37.36

                                                                              = $9.34

Therefore Cost Price of the 4 DVD                     = $37.36 - $9.34

                                                                              = $28.02

Sale tax percentage                                             =7% of the cost price

                                                                              = 7% of $37.36

                                                                              =$2.61

To the nearest cent                                             =$3

Therefore, the total cost of his order                  = $28.02 + $3

                                                                              = $31.02.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
