the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price should it be sold per kg to earn a profit of 20%
Answer:
7.2 rupees
Step-by-step explanation:
Given that at a loss of 10 percent which is 90% price, we have sugar sold at 5.4 rupees per k.g
Hence, at 100 percent we have => 5.4 × (100 ÷ 90 )= 6 rupees per kg.
Therefore, at 100 percent, where we have 6 rupees per kg, to make a profit of 20% we have
6 rupees per kg x 120% = 6 × 1.2 = 7.2 rupees per kg.
Hence, the final answer is 7.2 rupees per kg to make a profit of 20%.

Answer: y = -2x - 4
Step-by-step explanation:
This question asks that you give your answer in slope-intercept form, which is written as y = mx + b, where m is the slope, and b is the y-intercept.
In order to write an equation for this line in slope-intercept form, you need to find the slope and the y-intercept. You can find the slope by selecting any two clear points on the graph and finding the [change in y] ÷ [change in x].
For example, I’ll use (-3, 2) and (-2, 0):
Change in y: 2 - 0 = 2
Change in x: -3 - (-2) = -1
Change in y ÷ Change in x = 2 ÷ (-1) = -2
So, the slope, m, is -2. Finding b, or the y-intercept is a lot more straightforward; you just find where the line intercepts the y-axis, or when x = 0. Looking at the graph, we can see that the y-intercept is -4, so b = -4.
Now, we can put these together in an equation.
y = mx + b, where m = -2 and b = -4
y = -2x -4
