Question

devorys monthly budget
which of the following \expenses\ categories had the largest discrepancy between expected and actual amounts?
selling old textbooks
groceries
transportation
miscellaneous

Explanation:

Step1: Find differences for each category

For Rent: $|800 - 800|=0$
For Selling old textbooks: $|100 - 90| = 10$
For Scholarship: $|800 - 800|=0$
For Parental support: $|500 - 500|=0$
For Part - time job: $|1200 - 1100| = 100$
For Total income: $|(100 + 800+500 + 1200)-(90 + 800+500 + 1100)|=|2600 - 2490| = 110$
For Total expense: $|(800+2600)-(800 + 2490)|=|3400 - 3290|=110$

Step2: Compare differences

We have differences: 0, 10, 0, 0, 100, 110, 110. The largest difference is 110. The categories with a difference of 110 are Total income and Total expense. But among the given sub - categories, the largest difference is for Part - time job which is 100.

Answer:

Part - time job
