Question

Ross joined a 30-week weight loss challenge. He lost 10.4 pounds in the first 4 weeks. If he maintains this rate of weight loss, how many pounds would he lose at the end of the 30-week challenge?

Answer 1

To find the total weight Ross would lose at the end of a 30-week challenge, we calculate the number of 4-week periods within 30 weeks (7.5), then multiply this by his weight loss rate of 10.4 pounds. He would lose 78 pounds in total.

Step-by-step explanation:

Ross is losing weight at a rate of 10.4 pounds every 4 weeks. To compute how much weight Ross would lose at the end of the 30-week challenge, we first have to figure out how many 4-week periods exist in 30 weeks. We can do this by dividing 30 by 4, giving us 7.5. This means that there are 7.5 instances of 4-week periods in 30 weeks. By multiplying 7.5 with the rate of weight loss, 10.4 pounds, we find that Ross would lose a total of 78 pounds at the end of the 30 weeks, if he maintains the same rate of weight loss.
