My friend bought a headset on Ebay for $45 and then sold it for 40% more. How much did he sell it for?

63

Step-by-step explanation:

Multiply 0.4 by 45 (which is 18) then add that to 45.

Your friend sold it for $63 dollars

Step-by-step explanation:

40%= 40/100= .4

Multiply 45 by .4

= 18

Add 18 to 45

45+18=63

Your answer is 63

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
