Rachel paid $58 for a Blu-ray player that was on sale. She only paid 80% of the original cost. What was the original cost of the Blu-ray player?

$72.50

Step-by-step explanation:

To find the price of the original Blu-ray player, we first divide the price that Rachel paid by 8 , then multiply the result by 10 to get the full price.

58 / 8 = $7.25

$7.25 x 10 = $72.50

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

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
