s =

Answer

Find out the  markup and the selling price of the item.

To prove

As given

suit costing $120.00 marked up 50% on cost.

50% is written in the decimal form

= 0.50

Markup price (M) = 0.50 × 120.00

                            = 0.50 × 120

                            = $60

As 1 dollar = 100 cent

Markup price in cent (M) = 60 × 100

                                         = 6000 cent

Selling price (S) = Suit price + Markup price

                           = 120 + 60

                           = $180

Selling price in cent = 180 × 100

                                 = 18000 cent

Therefore the markup price (M) is 6000 cent and the selling price is 18000 cent .

(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
