My question is: A global gym decides to replace all of its cardio machines. They have 20 gyms. Each gym has 10 bikes, 5 treadmills, and 5 elliptical machines. The bikes cost $700 each. The treadmills cost 50% more than that. The elliptical machines are twice as expensive as the treadmills. How much does it cost to replace everything? Your thoughts:
The gym needs to buy 20 * 10 = 200 bikes. 20 * 5 = 100 each of treadmills and ellipticals. So the bikes cost 200 * 700 = $140,000. The treadmills cost 700 * 1.5 = $1,050 each. So they cost a total of 1050 * 100 = $105,000. The ellipticals each cost 1050 * 2 = $2100. So in total the ellipticals cost 2100 * 100 = $210,000. So the total cost of everything is 140,000 + 105,000 + 210,000 = $455,000. The final answer: 455000.
