Answer:
(-1,3)
Step-by-step explanation:
Graph the given system of equations
y=-x+2
make a table for each equation to graph it
Lets assume some value for x and find out y
x y=-x+2
-1 -(-1) + 2= 3
0 0+2 = 2
1 -1+2 = 1
Now make a table for second equation
y= 4x+7
Lets assume some value for x and find out y
x y= 4x+7
-1 4(-1) + 7= 3
0 4(0) + 7 = 7
1 4(1) + 7 = 11
The graph is attached below
Solution is (-1,3)

Given,
CP of cosmetics = Rs 360 per dozen
SP of a pair of cosmetics = Rs 80
To find,
The gain percent
Solution,
1 dozen = 12 items
CP of 1 cosmetic = 360/12 = Rs 30
SP of 1 cosmetic = 80/2 = Rs 40
Profit = SP-CP
= Rs 40 - Rs 30
= Rs 10
Profit percentage is given by :
So, the profit percentage is 33.34%.
