Answer: We know that Tonia eats 2 meals each day, breakfast and dinner. We also know that the total calories for each breakfast are 500.
If Tonia ate breakfast for 5 days, the total calories for breakfast would be 500 x 5 = 2500 calories.
We know that the total calories she ate for 5 days was 9000 and the number of calories for breakfast is 2500.
The number of calories for dinner over 5 days is 9000 - 2500 = 6500 calories.
To find the average number of calories Tonia consumed for dinner each day over the 5 days, we need to divide the total number of calories for dinner by the number of days:
average number of calories = 6500 / 5 = 1300 calories per day.
So Tonia consumed an average of 1300 calories per day for dinner over the 5 days.
