Based on the data provided if the customer went to the shop
and bought the potting soil and shrubs with the total bill of $94.75 and the
potting soil alone is for $11.50. We can determine the price of the shrubs in
total by deducting the 2 values. $94.75 - $11.50 = $83.25. Now that we have the
total amount of the shrubs to get the amount of each shrub we then divide the
total amount versus the number of shrubs which is 9, ergo $83.25/9 = 9.25 per
shrub.
