Question 733464: Julia and Mary each improved their yards by planting hostas and ivy. They bought their supplies from the same store. Julia spent $93 on 10 hostas and 9 pots of ivy. Mary spent $80 on 8 hostas and 8 pots of ivy. Find the cost one hosta and the cost of one pot of I've. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Julia and Mary each improved their yards by planting hostas and ivy. They bought their supplies from the same store. Julia spent $93 on 10 hostas and 9 pots of ivy. Mary spent $80 on 8 hostas and 8 pots of ivy. Find the cost one hosta and the cost of one pot of I've.
-------
Equations:
10h + 9p = 93 dollars
8h + 8p = 80 dollars
------
Modify:
Multiply thru top equation by 8
Multiply thru bottom equation by 10
-------
80h + 72p = 8*93
80h + 80p = 800
-----
Subtract and solve for "p":
8p = 56
p = $7.00 (price of one pot of ivy)
-----
Solve for "h":
8h + 8p = 80
h + p = 10
h = $3.00 (price of one hosta plant)
