Warehouse Club Membership Suppose that the annual fee for a warehouse club membership is $50 and that the reward rate on club purchases for the year is 1.6%.
Then the actual annual cost of a membership y, in dollars, for an amount of annual
club purchases x, in dollars, can be modeled by the following linear equation.
y = 50 – 0.016x
(a) Determine the actual annual cost of the membership if club purchases for the
year are $1500.
(b) What amount of club purchases would reduce the actual annual cost of the
membership to $0?
(c) If club purchases for the year exceed $3125, how is the actual annual member- ship cost affected?

yes

step-by-step explanation:

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
