I understood the question after the process of elimination was given and it makes sense because if the boxes were put into any other orders it would’ve resulted in a longer time than 43 minutes. The algebra was a bit confusing but I suppose it explains it easier for other people but the elimination made it pretty easy for me

I understood how u guys did the elimination and algebra, u guys have made it clear and organized. I found it easy to follow along. Well done!

good explanation
i was able to get how u guys got to solve the problem with algebra and simple process of elimination

i didnt understand how u got to the solution
you did elimination but then you skipped to the slution
i dont get how did that

Great Work!
I found the way you had the visual boxes on top and the difficult wording of the mathematical problem into a chart form very easy to understand. The use of the chart also helped to create very simple and understandable equations as well. The use of the process of elimination was very effective.
It was also great for you to support your answer through another method: algebra. By providing a ‘let-statement’ of both x small boxes and y large boxes it reallly helped to define the two variables; thus, making it extremely easy for me to understand due to the result of very simplistic equations. The steps of algrebra are also clearly shown and easy to follow through. By figuring out the appropriate pairs (x,y) after all the algebra done and the use of logic at the end (how the answer must take longer than 42 min to finish) was definitely helpful.
Very well done.
