Mr. Smith had 33 dozen cans. He sold 340 of them at $15 each. He sold the remaining cans at a discount of 20% each. How much money did he collect from selling the cans?
$

Mr. Smith collects $5748 from selling the can.

Step-by-step explanation:

Given total number of cans =  

Selling price of one can = $15.

Now remaining number of cans = total number of cans - sold number of cans =

For remaining number of cans he gives a discount of 20% each,

∴ Selling price of one can =  

∴ Selling price of 54 cans =  

So total money he earns =  .

Thus Mr. Smith earns $5748 by selling the cans.

(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
