The Marshall Company has a process costing system. All materials are added when the process is first begun. At the beginning of September, there were no units of product in process. During September 65,000 units were started; 6,500 of these were still in process at the end of September and were 3/5 finished. The equivalent units of material in September were:

The equivalent units of of materials in September = 62,400 units

Explanation:

Equivalent units are useful to apportion cost between work in progress and completed units. They are notional whole units which represent incomplete work

Equivalent Units = Degree of work completed (%) × inventory units

Items                        units            workings           Equivalent units

Completed unit        58,500      58,500× 100%  =     58,500

Closing WIP              6,500        6,500 × 3/5   =       3,900

Total equivalent units of materials                            62,400.

The equivalent units of of materials in September = 62,400 units

since the options are not listed, when you are working on your budget you should also add water, tv, internet, miscellaneous and your 'fun' money for in your budget. when budgeting, you need to allow for fun money, and mis/accidental money so that you stick to the budget and not go crazy because you feel strapped to the budget.
