10. A cell phone originally cost $550.79 and was marked up 5%. What is the new cost of the cell phone?

$578.33

Step-by-step explanation:

To get 5% of the original cost you need to multiply by 0.05

550.79 • 0.05 = 27.5395

27.5395 is 5% of 550.79

Since the price is marked up 5% you will need to add 27.5395 to 550.79

550.79 + 27.5395 = 578.3295

Then you will round your answer to 578.33

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
