A piece of equipment is expected to reduce defects by $100,000$ EGP per year for a construction item, for the next five years. In the following five years, it is expected to save only $30,000$ EGP per year, and to be sold for $70,000$ EGP at the end of the ten years of its life. How much can you afford to pay for this equipment now if you require a $20\%$ return on investment, and all expenses are assumed to be end$-$of$-$year amounts.
