Scenario #3 There are 3 identical microwaves available for purchase at 3 different
stores. The original prices of the microwaves are as follows:
Store #1: $395
Store #2: $375 Store #3: $410
The microwave at store #1 is on sale for 15% off. The original price of the
microwave at store #2 is 120% of the sales price. Both microwaves at
store #I and store #2 have an 8% tax attached, after the discounts are
applied Store #3 is online and does not have sales tax The original price of
the microwave is a 25% increase from the now advertised sales price
There is a $14.99 shipping and handling fee
Which store has the best deal?

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2
