Then the camper equal something like -7 and we KNOW our campers are worth more than that!

So I call #fakenews on the whole equation.
🤣🤣🤣

But, I heard that the new teaching of mathematics should emphasize the feel of it, not the accuracy!

Not my strong suit.

Put three zeros on the end and move to Canada and you can just about buy yourself one of them there Oliver’s. And on the way lay down 60,000 for a new Ford pickup parked at the horse track. Doesn’t run but they will call you when the part comes in, the mechanic gets trained, and it’s finally installed. You might miss the great fall camping in the smokies though.

Here is a clue:

Look carefully at the Oliver in the equation.

Do you see any differences between that one and the ones in the top row?

From my post #16 I've spotted the tire and window differences so I'll guess I'm on the right track. Is 89 correct? If not I'll have to recalculate

Yep. 89. Good job.

The 12 tires on the first line total 60.
The three windows on the first line equal 18.
The total for windows and tires on the first line is 78.
Line one total is 90… minus 78 for the tires and windows leaves 12 for the three trailers.
Or 4 for each trailer.

Summary:
Trailer = 4
Tire = 5
Window = 6

Now for the final line.. but note that there is no window and only two tires on the trailer! So… on the last line the trailer is one Trailer (4) + two tires (10) = 14

Now on the last line we have one tire (5) + trailer with two tires and no window (14) times one window (6).

... 5 + 14 x 6

Assuming algebraic operator precedence, first we do 14 times 6 = 84, then 84 + 5 = 89

I have edited this a bunch so maybe I will be quoted with a different answer but its late so.. final answer: 89
Yes. 89. It is tricky. Good job.

The equation and data provided is flawed. There ain’t no way the door’s window weighs more than a tire. It would therefore be logical that Oliver may be using the same convoluted math in pricing their product! LOL

Two observations….

First, as frustrating as this was (and it was frustrating!), when you get to my age and beyond, as I know some of you are, mental exercise becomes just as important as physical exercise. I glad that I stuck with it even after making many errors.

Second, For me at least this was unsolvable except for the help from others. It really shows the power of collaborative problem solving. Jon was the first to remind me of the algebraic order of operation precedence (multiply before adding) and to mention there were five tires and not three.

Wayne pointed out that the bottom camper is missing two tires and door window. I never noticed the difference in the bottom camper until it was pointed it out to me. I don’t recall him claiming 89 when I first read it but if his post is not edited then he gets credit for the first correct answer. But since everyone had to show their work when I was in school.. I did.

I figured it out in way less time than reading this would have taken, but did come up with the same answer, 89.

How do those trailers stay up without the front leveling jack all the way down?

Not exactly. It does put additional emphasis on the process and the student's ability to explain and defend the process. I noted a couple of different thought processes used to arrive at the correct answer to the Oliver problem.

That is extremely important in the real world in which there is no answer key. Results are verified by peer review of the process. Even when different processes lead to the same answer, it is valid to discuss which is the better (i.e., more simple, elegant, and/or transferrable) process.

I am sorry to have missed out on this fun exercise. Just getting home from a week of travel (sans trailer, unfortunately).

There owner is a retired plumber who had a lot of lead at the end of his career. He started making downrigger cannonball weights. He fills the fresh water tank with water and starts putting his cannonballs just behind the axles. When the trailer tips up in the front he goes around to the water tank drain and lets a little water out a cup at time. Shortly, balance is achieved and she sets on her wheels.
This I could do. The math, not so good. I can see wildlife at very good distance, but I am not a detail person.

The same way a Scamp does, or any other trailer?

My Scamp doesn't stay up at all without a tongue jack.
The hitch rests on the ground.

Do you have a magic spell you use to keep yours up?

If I had to figure out a math problem each time I would be in trouble. But, like everyone else I use the jack and a wooden block. Easy math!
