GIVING brainliest ND THANKS for best answers to both

A) 25% and C) 15

Step-by-step explanation:

both lines and boxes represent 25% and the first line ends at exactly 20 making everything under 20 25%

If you add the pink and purple lines that are both 12 emails and over then you get 15 people

hope that made somewhat sense XD

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
