The percent of discount on the backpack was 42.30%.
Step-by-step explanation:
Step 1:
From the given data, the original cost was $52 and it decreased to $30 due to a discount.
First, we need to determine the difference in values between the original price and the discounted price.
The difference between the prices
Step 2:
The percent decrease is given by dividing the difference in values by the original value multiplied by 100.
Percent decrease
Percent decrease
So there was a 42.30% discount on the backpack.
value of x = -2 and value of y = 6
The graph is shown in figure below.
The point of intersection is: (-2,6)
Step-by-step explanation:
We need to graph the system of linear equations.
Let:
First we will find the values of x and y to plot it on the graph.
-2x+y=10
x+2y=10
Multiply eq(2) by 2 and add both equations:
Putting value of y in eq(2)
So, value of x = -2 and value of y = 6
Now plot on the graph x=-2 and y=6
The graph is shown in figure below.
The point of intersection is: (-2,6)
Verifying the solution:
Verify the solution by putting value of x and y in eq(1) or 2
