Faced with declining enrollment and increased competition from not-for-profit organizations offering inexpensive art courses for new hobbyists, the for-profit Delta Academy of Art has steadfastly stayed true to its mission of offering high-quality classical art instruction for both beginners and advanced artists at high tuition. Delta has been noted for the excellence of its artistic training for decades. This is an example of:

Ahospital purchases a $500,000 magnetic resonance imaging (mri) machine that has a useful life of 9 years. the salvage value at the end of 9 years is $77,000. (a) write a linear equation that describes the value y (in dollars) of the mri machine in terms of the time t (in years), 0 ≤ t ≤ 9. (b) find the value, in dollars, of the machine after 6 years. $ (c) find the time, in years, when the value of the equipment will be $140,000. (round your answer to two decimal places.) yr
