Original cost (when the shop owner brought it) = $20,000
Profit amount = 20% of original cost
Discount rate = 10%
Solve:
First Step: Find the market price (before discount)
- $20, 000 × (1 + 20%) = $24, 000

You can discard the second and the fourth systems because they do not have the form established from the statement.
The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.
The third system is
y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.
Answer: y = 7.5x and y = 5..5x + 10
The slope of line that passes through given points is -1/2
Step-by-step explanation:
The formula for slope is:
Given points are:
(-2,-1) = (x1,y1)
(2,-3) = (x2,y2)
Putting the values in the formula of slope
m =
The slope of line that passes through given points is -1/2
