A department store buys 100 shirts at a cost of $1,600 and sells them at a selling price of $20 each. Find the percent markup

25%

Step-by-step explanation:

1,600/100=.75

100-75=25

16*.25=4

16+4=20

Hope this helps. :)

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

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
