22cm is the greatest
It should be greater than17(20-3)
and smaller than 23(20+3)
Answer:
The equation is y = 3/5x - 6
Step-by-step explanation:
First we have to find the slope of the line. In order to do so, solve the first equation for y.
3x - 5y = 7
-5y = -3x + 7
y = 3/5x + 7/-5
This gives us a slope of 3/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.
y - y1 = m(x - x1)
y - -6 = 3/5(x - 0)
y + 6 = 3/5x
y = 3/5x - 6
Let the amount be x.
6% for the first 160000
= 6/100 * 160000 = 9600
4% for any amount exceeding 160000.
= 4/100 * (x -160000) = 0.04(x-160000)
The sum of both commission should be equal to 10560.
9600 + 0.04(x -160000) = 10560
0.04(x -160000) = 10560 - 9600
0.04(x -160000) = 960 Divide by 0.04.
(x -160000) = 960/0.04
(x -160000) = 24000
x = 24000 + 160000 = 184000.
Selling price = 184000
