Thought Process:

The solution to this can be found through plotting both of these functions and shading each region above or below the lines (as per the greater and less than signs given)

the region that overlaps both of the above shaded region is the solution set for all ordered pairs that satisfy the two inequalities.

Solution:

let's start by plotting

y > -\dfrac{1}{3}x + 2

it's the same as plotting y = -\dfrac{1}{3}x + 2, but '>' sign suggests to shade everything above this line.

<u>side note:</u>

'>' excludes every ordered pair in the line,

'\leq' includes every ordered pair in the line,

coming back to our solution:

now let's plot the other equation

y > 2x + 3

it's the same as plotting  y = 2x + 3, but '<' sign suggests to shade the area below this line.

The solution set is the area that is overlapped by the two shaded regions.

So every ordered pair (or coordinate (x,y)) that lies within this overlapped shaded region, excluding the points that lie on the lines themselves, satisfy the given two inequalities

Answer:

1) $101,400

2) $27,000

Step-by-step explanation:

1) For this, we can first find how much she makes in a year from her salary alone:

$2,200×12= $26400.

Now, she also received a commission of 2.5%, so we can take this percentage from 3 million to find the total from commission:

3,000,000×0.025= $75,000

Adding these two gives us a total of $101400.

2) We can use the Simple Interest Formula to solve this (I= Prt). Plug in the values given to give us:

I= 5000(1.08)(5)

I= $27000

A DVD player costs $96.34, with sales tax included. What is the original price of the DVD player if the sales tax rate is 8.25%?
Margaret [11]

The original price of the DVD player if the sales tax rate is 8.25% is $88.79

<h3>Sales tax</h3>

  • Cost of DVD player including tax = $96.34
  • Sales tax = 8.25%
  • Original cost = 8.25%

Total cost = original cost + (sales tax × original cost

96.34 = x + (8.5% × x)

96.34 = x + (0.085 × x)

96.34 = x + 0.085x

96.34 = 1.085x

x = 96.34 / 1.085

x = 88.7926267281105

Approximately,

x = $88.79
