A physician offers two diet plans:
| Plan 1 | Plan 2 | |
|---|---|---|
| Length | 10 weeks | 14 weeks |
| Daily exercise | 1 hr | 30 min |
| Weight loss per week | 3 lb | 2 lb |
Select all correct signed numbers below.
Correct Answer
(1) Plan 1 expected loss: \(-30\) lb
(2) Plan 2 expected loss: \(-28\) lb
Explanation
Plan 1: \(10 \times (-3) = -30\) lb
Plan 2: \(14 \times (-2) = -28\) lb
Plan 1 produces a greater loss (\(-30\) lb vs \(-28\) lb), though it requires more exercise per day.
