Amy purchased a prepaid phone card for $20 Long distance calls cost $.22 a minute using this card Amy use her card only wants to make a long distance call if the remaining credit of her card is $14.72 how many minutes did her car last

24

Step-by-step explanation:

$20 - $14.72 = $5.28

$5.28 ÷ $0.22=24

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.
