Final answer:
Miya should aim to eat between 423 grams and 705 grams of carbohydrates per day based on the recommendation of 6 to 10 g of carbohydrates per kilogram of body weight.
Step-by-step explanation:
To calculate the number of grams of carbohydrates per day that Miya should be eating, we first need to convert her weight from pounds to kilograms. Given that 1 kg = 2.2 pounds, Miya's weight in kilograms is 155 pounds / 2.2 = 70.45 kg (rounded to two decimal places).
Next, we can use the range recommended by sports nutrition professionals of 6 to 10 g of carbohydrates per kilogram of body weight. Multiplying Miya's weight in kilograms by the lower and upper ends of this range, we get:
Minimum carbohydrate intake: 70.45 kg * 6 g/kg = 422.7 g
Maximum carbohydrate intake: 70.45 kg * 10 g/kg = 704.5 g
Therefore, using this recommendation, Miya should aim to eat between 423 grams and 705 grams of carbohydrate per day.
