28X0.86 = 24.08, therefore Joe made $24.08
The answer is A. u do the othe angle and add it to the fisrt one
Dy/dx, ie., the difference in y divided by the difference in x. If you have two points A and B, sort them in ascending order of x.
dx = 5 - -3 = 8 (x coordinates of B minus x coordinate of A)
dy = -3 - 5 = -8 (y coordinate of B minus y coordinate of A)
dy/dx = -1
So the slope is -1. The equation of the line is y=2-x.
Answer:
Profit = 75
Step-by-step explanation:
Selling price of 3 oranges = 2
There are 210÷3 = 70 set of oranges
Selling price of 1 set (3 oranges) of orange = 2
Selling price of 70 set of oranges = 70 * 2 = 140
Cost of 210 oranges = 65
Profit = selling price - cost price
= 140 - 65
= 75
