Answer:
50 A and 50 B
Step-by-step explanation:
A》20
B》10
A + B》100 (for pants)
A + 3B》200 (for shirts)
A = 20
A + 3B = 200
3B = 180
B = 60
(20,60)
B = 10
A + B = 100
A = 90
(90,10)
A + B = 100
A = 100 - B
A + 3B = 200
100 - B + 3B = 200
2B = 100
B = 50
A = 100 - 50 = 50
(50,50)
Revenue:
30A + 50B
(20,10): 30(20) + 50(20)
= 1,100
(20, 60): 30(20) + 50(60)
= 3,600
(90,10): 30(90) + 50(10)
= 3,200
(50,50): 30(50) + 50(50)
= 4,000
Answer:
x = -5/7
Step-by-step explanation:
8 1
---------- = ----------
x+3 x+1
Using cross products
8 (x+1) = 1 (x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x-x+3
7x+8 =3
Subtract 8 from each side
7x +8-8 =3-8
7x = -5
Divide each side by 7
7x/7 = -5/7
x = -5/7
