Bill spent $108 on 8 hostas and 5 shrubs. What is the cost of one hosta and the cost of one shrub? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x=hostas cost
y=shrubs cost
7x+10y=117
8x+5y=108
======
7x+10y=117
-16x-10y=-216, multiplying the bottom by (-2)
-9x=-99
x=11
substitute into first
77+10y=117
y=4
=====
check with second
88+20=108
hosts are $11
shrubs are $4
