Duval County Landscaping uses two different sized trucks to deliver mulch. The first truck can transport x cubic yards of mulch,
Gre4nikov [31]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of cubic yards of mulch that first truck can transport
 y: number of cubic yards of mulch that second truck can transport
 Now we write the expression.
 The first truck makes 12 trips to a job site:
 12x

 The second makes 14 trips:
 14y

 The difference between the first truck and the second truck is:
 12x - 14y
 Answer:
 
An expression that represents the difference in the total number of cubic yards that the first truck delivers compared to the second is:
 
12x - 14y
