Homework Help Overview

The problem involves a zookeeper spending a total of $133.10 on bananas and nuts, with the condition that he buys 8 kilograms more bananas than nuts. The costs per kilogram for bananas and nuts are given, and participants are tasked with forming equations to determine the quantities purchased.

Discussion Character

  • Exploratory, Mathematical reasoning, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants discuss the formation of simultaneous equations based on the problem statement, with some suggesting different interpretations of the variables representing weight versus cost.

Discussion Status

The discussion has evolved with participants attempting to clarify the relationships between the quantities of bananas and nuts, as well as their costs. Some have pointed out the need to define variables explicitly to avoid confusion, while others are exploring how to structure the equations correctly.

Contextual Notes

There is a noted confusion regarding the units of measurement (weight versus cost), which has led to some misinterpretations in forming the equations. Participants are encouraged to revisit their initial assumptions and clarify the definitions of their variables.

Um what? Have you solved the two equations B= N+ 8 and 2.20B+ 4.80N= 133.10?
Since B= N+8, replace the B in the second equation with that: 2.20(N+ 8)+ 4.80N= 133.10. Now solve that equation for N.
