and tea.


((Plz do step by step for me to understand in a better way))​

Answer 1

Answer:

rate of tea per kg    =200

rate of sugar per kg=25

Step-by-step explanation:

rate of tea per kg    =x

rate of sugar per kg=y

given

x=8y

y=x/8

3x+2y=650(equation 1)

3x+2x/8=650

24x+2x/8=650

26x=650*8

x=650*8/26

x=200

substitute in equation 1

3(200)+2y=650

600+2y=650

2y=600-650

2y=50

y=25
