William was driving back to the office from his off$-$site construction job on Friday. He had put in a long week and just wanted to go home. But a text from Michael back in the office reminded him to enter his weekly mileage$-$the accountants needed to finish the company's total fleet expenses for its quarterly income statement$-$and the performance evaluation meeting was on Monday. William was frustrated that his weekend was now going to be delayed because of this data entry business. He wondered why Michael couldn't just use the fuel cost for the income statement.

In the end, William complied with Michael's request and input his mileage information. William's mileage was added to the other vehicles' mileage information, with the quarterly totals listed below. Total fleet expenses on the income statement are a combination of the five costs shown here.

$\backslash$table$[[,\backslash$table$[[$Vehicle$],[$Insurance$]],\backslash$table$[[$Registration$],[$Fees$]],$Fuel,$\backslash$table$[[$Depreciation$],[($Shed & Vehicles$)]],\backslash$table$[[$Vehicle$],[$Maintenance$]],\backslash$table$[[$Miles$],[$Driven$]]],[$Q$1,$$$1,800,$$$1,300,$$$3,410,$$$5,300,$$$2,945,31,000],[$Q$2,1,800,1,300,3,850,5,300,3,115,35,000],[$Q$3,1,800,1,300,3,300,5,300,2,850,30,000],[$Q$4,1,800,1,300,3,960,5,300,3,348,36,000]]$

Place all of this fleet expense information into one final cost function where is fleet total expenses and X is the number of miles driven right out the formula in Y equals M times X plus B format
