Linda is buying boxes of ice cream sandwiches for her class party. she has to decide how many boxes she should purchase. a formula for this scenario is: z=ax/y where z=number of boxes, a= number of bars each student will eat, x= number of students at the party, y= number of ice cream bars per box. linda has 15 students in her class, and she wants each student to have 2 ice cream sandwiches. if there are 10 sandwiches in a box, how many boxes should linda buy?

a = 2

x = 15

y = 10

Z= 2x15/10 = 3

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.
