By selling an exhaust fan for Rs. 1470, a man gains profit of 1/6 of its cost price. Find its cost price.

Rs 1260

Step-by-step explanation:

let x be the cost price , then

x + x = 1470 , that is

x = 1470 ( multiply both sides by 6 to clear the fraction )

7x = 8820 ( divide both sides by 7 )

x = 1260

The cost price was Rs 1260

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
