Q: A person’s Basal Metabolic Rate (BMR) can be estimated using the following formula: $$BMR = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (years)} + 5 ($$for men). If a 30-year-old man weighs 70 kg and is 175 cm tall, what is his BMR?

$$BMR = 10 \times 70 + 6.25 \times 175 - 5 \times 30 + 5 = 700 + 1093.75 - 150 + 5 = 1648.75$$
