Answer
To represent the story situation with a bar model:
- Total Payment: Draw a bar representing $200.
- Cost of Dumping: Subtract the total cost ($88 × tons dumped) from the total payment.
- Change Received: The remaining part of the bar shows the change Mr. Jones gets.
For example, if Mr. Jones dumped 2 tons:
- Cost: $176
- Change: $24
So, the bar model would show $176 subtracted from $200, leaving $24 as change.

To understand Mr. Jones’s situation better, let’s break it down visually! Imagine a bar representing the total amount Mr. Jones gave to the landfill attendant, which is
. From this, we’ll subtract the cost of dumping the trash. If Mr. Jones dumped, say,
tons of trash, the cost is
. For instance, if he dumped 2 tons, you’d have a bar of
and a smaller bar of
(which is
). The remaining part of the bar would represent his change!
Now, when thinking about how much change Mr. Jones should receive, don’t forget to set up the formula! It’s as easy as taking the total he provided and subtracting the total cost of dumping his trash ($200 - $88x). This way, you can easily find out how much cash he gets back—just remember to double-check your math to avoid penny pinching!
