Desmond paid 8.5% sales tax when he bought a new phone. The sales tax was $12.75. What was the total cost of the phone, including tax?

$162.75

Step-by-step explanation:

8.5% = 0.085

12.75 / 0.085 = 150 (price before tax)

150 + 12.75 = 162.75

mark as brainiest if it helps and accept my friend request

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.
