A sailboat begins a voyage with 145 lb of food. The crew plans to eat a total of 15 lb of food per day. The crew plans to have 25 lb
of food remaining when they end their voyage. How many days does the crew
expect their voyage to last?

The crew expects their voyage to last 8 days.

Step-by-step explanation:

There are initially 145 lb of food in the sailboat.

The crew plans to eat 15 lb of food per day, and they want to leave 25 lb of food remaining when they end the voyage.

The amount of food to eat during the voyage is 145 - 25 = 120 lb.

Since the daily consumption of food is 15 lb, there is enough food for 120/15 = 8 days.

The crew expects their voyage to last 8 days.
