Answer:
Children = 2.25 ; Adult = 3.5
Explanation:
Given that :
Admission prices :
Let :
Senior fees = x
Children fees = y
2x + 9y = 36 - - - - - (1)
4x + 6y = 30 - - - - - (2)
Multiply (1) by 2 and (2) by 1
4x + 18y = 72 - - - (3)
4x + 6y = 30 - - - (4)
Subtract 4 from 3
12y = 42
y = 42 /12
y = 3.5
Put y = 3.5 in (2)
4x + 6(3.5) = 30
4x + 21 = 30
4x = 30 - 21
4x = 9
x = 9/4
x = 2.25
Children = 2.25 ; Adult = 3.5
Are there any other options? Both statements presented are accurate.
Answer: The humus tend to increase with the clay content of the soil because the clay soil absorbs much water.
The soil containing humus is dry and friable and the clay soil is flat and hard where there is no space for further decomposition.
The clay particles stick together and does not allow the particles to move in the soil.
The humus has 30 to 40 per cent more attraction to nutrients than clay soil.
