An appliance salesperson earned $32.80 in commission for selling a refrigerator for $820. At that rate, how much would the salesperson earn in commission for selling a microwave oven for $340?

Salesperson would earn $13.6 in commission for selling a microwave oven for $340.  

Step-by-step explanation:

We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.

We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.

Firstly, we will the find the rate at which the salesperson gets a commission in % terms.

So, Percentage rate of commission is given by;

Rate of commission=(Commission earned ÷ Selling Price of refrigerator)  100

                                =  =  = 4%

Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;

Commission earned  for selling a microwave oven = 4% of Selling price of microwave oven

                                  =   = $13.6

Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.

i take 75 plus 50.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
