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 $700 each.  The treadmills cost 50% more than that.  The elliptical machines are twice as expensive as the treadmills.  How much does it cost to replace everything?
The gym needs to buy 20*10=
<gadget id="calculator">20*10</gadget>
<output>200</output>
200 bikes
20*5=
<gadget id="calculator">20*5</gadget>
<output>100</output>
100 each of treadmills and ellipticals.
So the bikes cost 200*700=$
<gadget id="calculator">200*700</gadget>
<output>140_000</output>
140,000.
The treadmills cost 700*1.5=$
<gadget id="calculator">700*1.5</gadget>
<output>1_050</output>
1,050 each.
So they cost a total of 1050*100=$
<gadget id="calculator">1050*100</gadget>
<output>105_000</output>
105,000.
The ellipticals each cost 1050*2=$
<gadget id="calculator">1050*2</gadget>
<output>2_100</output>
2100.
So in total the ellipticals cost 2100*100=$
<gadget id="calculator">2100*100</gadget>
<output>210_000</output>
210,000.
So the total cost of everything is 140,000+105,000+210,000=$
<gadget id="calculator">140000+105000+210000</gadget>
<output>455_000</output>
455,000.

<result>455_000</result>
