Acustomer went to a garden shop and bought some potting soil for $17.50 and 4 shrubs. the total bill was $53.50. write and solve an equation to find the price of each scrub.

So what we know that the customer bought 17. 50 then 4 shrubs. And the total bill is $53.50. 

First we need to subract 53.50 (the bill) with 17.50 (amount spend on potting soil).
53.50 - 17.50 = 36

Now we know that the leftover money is $36.00. Next we are going to divide the 36.00 (remaining money) with 4 (amount of shrubs bought).
36.00 / 4 = 9

The amount spend on each shrub would be $9.00.

Hope this helps!

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
