Theodore and sarah have a small business selling custom-made t-shirts. they currently sell 150 shirts per month and charge $10 per t-shirt. sarah thinks they can increase their revenue by increasing their selling price, but theodore knows from experience that each $1 increase in price will decrease the number of t-shirts they sell by 8 shirts per month. find an expression for the total monthly revenue theodore and sarah’s business can generate if they change the selling price of their t-shirts. let x represent the number of $1 increases in the price of the t-shirts

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
