Answer: One hosta= $8
One shrub = $10
Step-by-step explanation:
Let the cost of one hostas be h
Let th cost of one shrub be s.
The question can be rewritten into am equation as:
2h + 7s = 86 .......... equation i
8h + 4s = 104 ........ equation ii
Multiply equation i by 8
Multiply equation ii by 2
16h + 56s = 688 ...... equation iii
16h + 8s = 208 ........ equation iv
Subtract equation iv from iii
48s = 480
s = 480/48
s = 10
One shrub cost $10
Put the value of one shrub into equation ii
8h + 4s = 104
8h + 4(10) = 104
8h + 40 = 104
8h = 104 - 40
8h = 64
h = 64/8
h = $8
One hostas cost $8
