Orlando lives in south dakota and pays 4% in sales tax. he bought a refrigerator, and the amount he paid after sales tax was applied was $2749.87. what was the approximate cost of the refrigerator before sales tax was applied? a.$2644.11 b.$2738.91 c.$2760.87 d.$2859.86

Option A. $2644.11

Step-by-step explanation:

Orlando lives in South Dakota and pays 4% in sales tax.

He bought a refrigerator, and the amount he paid after sales tax = $2749.87

Let the cost of refrigerator before sales tax be 'x'

Therefore, x + (4% of x) = 2749.87

x + 0.04x = 2749.87

x( 1+0.04 ) = 2749.87

1.04x = 2749.87

x =

x = 2644.105769 ≈ $2644.11

The cost of the refrigerator was $2644.11 before sales tax was applied.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

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
