Asanji and Ndiba each improved their yards by planting rose bushes and ornamental grass,
They bought their supplies from the same store.
Asanji spent $11 on 1 rose bush and 2 bunches of ornamental grass.
Ndiba spent $23 on 5 rose bushes and 2 bunches of ornamental grass.
Find the cost of one rose bush and the cost of one bunch of oranamental grass.

This problem is for MENTAL solution.
The difference between their purchases is 4 rose bushes and 23-11 = 12 dollars.
Hence, one rose bush costs 12/4 = 3 dollars.
Then 2 bushes of ornamental grass costs 11 - 3 = 8 dollars --- hence, one
bush of ornamental grass costs 8/2 = 4 dollars.
Solved.
