Question

Sally is on a diet to lose some weight. She is losing weight at a rate of 2 pounds

Answer 1

Answer:

204-2w=180 (where w is the amount of weeks)

w=12

(If you need the total amount, including the 6 weeks, add 6 to 12 to get 18)

Step-by-step explanation:

Sally is technically starting at 204 pounds and losing 2 per week. Therefore, that can be modeled as 204-2w because if she loses 2 per week you subtract that from the starting weight. You want to then set it equal to 180 and solve for w.

$204-2w=180\\-2w=-24\\w=12$
