The number of pieces of chicken in each plate = 
The number of pieces of rolls in each plate = 
So, the greatest number of plates Lenin can prepare = 4
and there will be 3 chickens and 4 rolls in each plate.

Answer: she needs to buy 80kg of
dark chocolate and 70kg of milk chocolate.
Step-by-step explanation:
Let d represent the number of kilograms of dark chocolate that she buys.
Let m represent be the number of kilograms of milk chocolate that she buys.
She wants to buy 10g more of dark chocolate than milk chocolate. This means that
x = y + 10
She needs 150kg of chocolate in total for her next order. This means that
x + y = 150 - - - - - - - - - - - --1
Substituting x = y + 10 into equation 1, it becomes
y + 10 + y = 150
2y + 10 = 150
2y = 150 - 10 = 140
y = 140/2 = 70
x = y + 10 = 70 + 10
x = 80
