The cost of one rose bush is $2 and one day lily is $10.
Step-by-step explanation:
Let,
Cost of one rose bush = x
Cost of one day lily = y
According to given statement;
7x+6y=74 Eqn 1
7x+y=24 Eqn 2
Subtracting Eqn 2 from Eqn 1

Dividing both sides by 5

Putting y=10 in Eqn 1

Dividing both sides by 7

The cost of one rose bush is $2 and one day lily is $10.
