Mr. Jones is covered by a group health plan that has a $350 deductible and a 30% coinsurance provision for covered services provided by out-of-network providers. To date, Mr. Jones has not met any portion of this deductible. If Mr. Jones has incurred total charges amounting to $2,000 for a service provided out-of-network and the plan's allowable charges are $1,600, what are Mr. Jones's out-of-pocket expenses

You are the manager of a large crude-oil refinery. as part of the refining process, a certain heat exchanger (operated at high temperatures and with abrasive material flowing through it) must be replaced every year. the replacement and downtime cost in the first year is $165 comma 000. this cost is expected to increase due to inflation at a rate of 7% per year for six years (i. e. until the eoy 7), at which time this particular heat exchanger will no longer be needed. if the company's cost of capital is 15% per year, how much could you afford to spend for a higher quality heat exchanger so that these annual replacement and downtime costs could be eliminated?
