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?
Let's be accurate as possible and think first.
455000
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 answer is 455000
