Brian has decided he would like to negotiate on a car with a $32,000 sticker price. If the dealer's cost on this car is 15 percent lower than the sticker price, Brian should be able to negotiate a price somewhat higher than

Brian should be able to negotiate a price higher than $27,200.

Step-by-step explanation:

Given:

Sticker price of the car = $32,000

Cost of the car = 15% lower than the sticker price.

We need to find the cost of the car as negotiation price needs to be higher than the cost price.

Solution:

First we find the cost of the car.

In the above statement, the cost of the car is 15% lower than the sticker price, so we use the percentage formula for cost of the car.

Using percentage formula.

Now, we substitute percentage value = 15 and Sticker cost = $32,000

Now, we divide 32,000 by 100

So, cost of the car is equal to $27,200

Therefore, Brian should be able to negotiate a price higher than $27,200.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
