The first intersellar tourist shuttle is ready for departure to the planets Zerbo, Yorx, Greebe, and Blinko. Tourists from all over Earth are waiting to board. They are eager to shop in the stores on the different planets. As they shop they will have to remember that 9 Zebro dollars have the same amount as 3 Yorx dollars; 6 Blinko dollars have the same amount as 5 Greebe dollars; and 10 Blinko dollars have the same value as 2 Zebro dollars. A solar-powered dog polisher on Blinko costs 90 Blinko dollars. How much would it cost in Yorx dollars and in Greebe dollars?

6 Yorx
75 Greebe
9 Zebro = 3 Yorx
6 Blinko = 5 Greebe
10 Blinko = 2 Zebro
therefore
90 Blinko = 18 Zebro = 6 Yorx =75 Greebe

9Z = 3Y
6B = 5G
10B = 2Z
DP = 90B = ??Y = ??G
B = 5/6 G
DP = 90 * 5/6 G, or 75G (75 Greebe dollars)
Z = 3/9 Y, or Z = 1/3 Y
10B = 2 * 1/3 Y, or 10B = 2/3 Y
B = 2/30 Y, or B = 1/15 Y
DP = 90 * 1/15 Y, or 6Y (6 Yorx dollars)

enable the quantity of 30% be x, then something is 20-x of the 70% 30 x + (20-x) 70 = 20(50) -40x + 1400 = one thousand x = 10 of the 30% 20-x = 10 of the 70% considering the fact that 50% is halfway between 30% and 70%, this makes ideal experience !

75 g
30 y
6b=5g
9z=3y
10b=2z
90b=18z
90z=30y
10b=2z
15x5=75g
3x10=30y
