Seems like all the findings in green are not required.
For more challenge, question can ask to find the cost of 1 Bowl ($156/13=$12), given same information provided in this question.
For higher challenge, don’t provide cost of each plate. Just say the difference between cost of each plate and bowl is $5 and ask which item is more expensive and find the cost of each item. (Big diff/small diff= ($156-$91)/$5 = 13pcs per set and …)
Either way, the tabulation and working can be similarly used. It’s good to drill together with your kids into details within same question to understand what each data represents, so they know how to use and manipulate the data to their advantage. Process over Final outcome, Quality over Quanity. Have some fun in Maths.
