Reasoning & answer: CoT: The cheap gym cost 10 * 12 = $120 for monthly fees. So the total cost was 120 + 50 = $170. The more expensive gym cost 3 * 10 = $30 per month. That means the sign - up fee was 30 * 4 = $120. The monthly fees for the expensive gym comes out to 30 * 12 = $360 per year. So the total cost for the expensive gym was 360 + 120 = $480. So his total cost was 480 + 170 = $650.
The answer: 650
