Josie has already consumed 1 calorie during the day, and she will get 24 additional calories from each late-night snack seats. how many late-night snacks does josie have to eat to consume a total of 49 calories?

Toatl calories is 49.

She ate 1 during the day, so subtract 1 from the total to find how many calories she needs from her snacks :

49 -1 = 48 calories.

Each snack is 24 calories, so divide the number of calories she needs by 24 to find the number of snacks:

48 calories / 24 calories per snack = 2 snacks.
