A friend purchases items from a website and resells them on her own website. She typically marks up her merchandise 40%. If she purchased an item for 15$, what price should she set for the item?

$21

Step-by-step explanation:

Step one:

given

she purchased an item for $15

marks up her merchandise 40%.

let us find 40% of $15

and add the answer to the initial price of the item

Step two:

40/100*15

=0.4*15

=$6

Hence the price should she set for the item is

=15+6

=$21

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
