Back in 1990 there were lots of Dunkin Donuts stores near
DUNKIN' Elmhurst
, but Starbucks was new to the Midwest. Within a
DONUTS 20 mile radius of Elmhurst there were 205 Dunkin Donuts
shops, and the number of stores was growing at a rate of
2.7% per year. There were only 8 Starbucks in that same
area, but new stores opened often and the number of
Starbucks shops was increasing 24% each year.

Write two equations to model this situation, one about Dunkin Donuts and we about Starbucks.
Let x = the number of years after 1990 and let y = the number of stores.

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.
