Answer:
The cost of one rose bush is $2 and the cost of one shrub is $2.
Step-by-step explanation:
Let r represent the cost of 1 rose bush and s the cost of 1 shrub.
Kali's expenditure
2r + 14s = 32
Divide each term by 2
r + 7s = 16 ------ (i)
Kim's expenditure
11r + 2s = 26 ------ (ii)
From equation (i)
r = 16 - 7s
11(16 - 7s) + 2s = 26
176 - 77s + 2s = 26
-75s = 26 - 176
-75s = -150
s = -150/-75 = 2
r = 16 - 7s = 16 - 7(2) = 16 - 14 = 2
The cost of one rose bush is $2 and the cost of one shrub is $2
