Microsurfacing is part of a pavement restoration and maintenance program that seals the surface of a street that has minor cracking to prevent water from penetrating into the base material. The annual cost of equipment (trucks, tanks, valves, etc.) is \$109,000 per year and the material cost is \$2.75 per square yard. Alternatively, regular street resrufacingrequires equipment that has a first cost of \$225,000 with a 15-year life and no salvage value. The variable cost for regular resurfacing is \$13 per square yard. At an interest rate of 8% per year, how many square yards per year must be resurfaced for the two methods to breakeven?

This is mostly an accounting problem! I'm not an accountant, but will take a crack at it!

There are as many as half a dozen methods of depreciating an asset, but I'm going to use the method of amortization of the \$225,000 initial expenditure at the given rate of 8%. When you amortize it over 15 years, you get an equal annual depreciated amount of \$26,286.65.

Let the number of square yards paved, in both given scenarios in the question = Y, then we have this:

\$109,000 + \$2.75Y = \$26,286.65 + \$13Y, solve for Y

\$109,000 - \$26,286.65 =\$13Y - \$2.75Y

\$82,713.35 = \$10.25Y

Y = \$82,713.35 / \$10.25

Y = ~8,070 Square yards for the 2 methods to break even.

Note: It depends on the depreciation method you use, the answer will be different in each case. Use the method that is recommended in your textbook, or by your teacher.
