Answer:
Cost Price = Rs 10000
Step-by-step explanation:
Assume:
Cost of the item = x
Item was sold at a loss of 20%:
Loss = 20% of x = 0.2x
Item sold = x - 0.2x = 0.8x
Item sold at a profit of 10%:
Profit = 10% of x = 0.1x
item sold = x + 0.1x = 1.1x
Solve:
Difference = 1.1x - 0.8x = 0.3x
0.3x = Rs 3000
x = Rs 3000 ÷ 0.3
x = Rs 10000
D, it’s a function because the Y and X values have its own numbers , and vertical are functions . Horizontal is not a function
<span>The equation of any straight line, called a linear equation,can be written as:y=mx+b, where m is the slope is the slope of the line and b is the y intercept. The y- intercept of the line is the value of y at the point where the line crosses the y axis</span><span>.
I hope this helps :)
