The zookeeper's problem involves spending $133.10 on bananas and nuts, with 8 kilograms more bananas than nuts. The equations to solve are B = N + 8 (where B is the weight of bananas and N is the weight of nuts) and 2.20B + 4.80N = 133.10, representing the total cost. After substituting B in the second equation, the solution leads to determining the weights of both bananas and nuts. Properly defining the variables is crucial for avoiding confusion in solving the problem. The discussion highlights the importance of clarity in mathematical problems involving different units.

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.
