An electronics store makes a profit of $61 for every standard CD player sold and $66 for every portable CD player sold. The manager's target is to make at least $405 a day on
sales from standard and portable CD players. Write an inequality that represents the
numbers of both kinds of CD players that can be sold to reach or beat the sales target.
Let s represent the number of standard CD players sold and p represent the number of
portable CD players sold. Then graph the inequality.

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

c

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
