How did you work out such a math problem: a catty of apple 3 yuan, a catty of banana 5 yuan, a catty of orange * yuan, 100 yuan?
Settings? 2X banana? Do you have 5X apples? Is the orange10x2x+5x+10x =170? 17x =170x =10 banana 2X=20 apples 5X=50 oranges 10X= 100.
2.？ Set the unit price of apples at X yuan per kilogram? 3X+2.5* 1.6X=3.5？ 7X=3.5 X=0.5
0.5 yuan per kilogram of apples? Oranges 1.6*0.5= 0.8 yuan per kilogram?
So cheap? I also buy-? -
