Answer:
$9
Step-by-step explanation:
Let [tex]x[/tex] be the price of each shrub.
- 4 shrubs at [tex]x[/tex] each costs [tex]4x[/tex] dollars
- Potting soil is $17.50
Hence, total cost is the expression [tex]17.5+4x[/tex]
We know that total bill is $53.50, so we can equate it to the expression:
[tex]17.50+4x=53.50[/tex]
This equation can be solved for [tex]x[/tex] to find cost of each shrub.
Solving for [tex]x[/tex] gives us:
[tex]17.50+4x=53.50\\4x=53.50-17.50\\4x=36\\x=\frac{36}{4}\\x=9[/tex]
So price of each shrub is $9
