Answer 1

a. eat 2750 calories per day and exercise enough to burn 500 calories per day

Step-by-step explanation:

To lose 1 lb of weight= - 3500 cal

Arthur consumes 3000 calories per day

To lose 12 lb in 8 weeks (56 days) = - 3500 cal x 12 lb = - 42,000 cal

Calorie consumption and burn off per day = 2750 cal - 500 cal = 2250 cal

Arthur's consumption = Daily normal calorie intake - Daily calorie intake for diet >>

3000 cal - 2250 cal = 750 cal per day >> 750 cal x 56 days = 42,000 cal
