did peter beat his calorie goal that day? explain.

Explanation:

Step1: Calculate total calories consumed

Sum up the calories from each meal and snack.
$400 + 200+500 + 600+200=1900$ calories

Step2: Calculate total calories burned

Sum up the calories burned from each activity.
$90+100 + 120=310$ calories

Step3: Determine net calorie change

Subtract calories burned from calories consumed.
$1900 - 310=1590$ calories

Step4: Answer Part A

Peter needs to burn 3500 more calories than he takes in each week for weight - loss. Since this is for one day, if we assume a 7 - day week, he needs to burn an average of $\frac{3500}{7}=500$ more calories per day than he takes in. He consumed 1900 calories and burned 310 calories. To burn 500 more than he takes in, he should burn $1900 + 500=2400$ calories. Currently, he burned 310 calories, so he needs to burn $2400-310 = 2090$ more calories.

Step5: Answer Part B

To maintain his weight, he needs to have a net calorie intake of 0 (calories in = calories out). He consumes 1900 calories per day. So his new daily calorie - burning goal should be 1900 calories.

Step6: Answer Part C

We calculated the total calories consumed as 1900 and total calories burned as 310. The net calorie intake for the day is $1900 - 310=1590$ calories. Since he needs to burn 3500 more calories than he takes in per week (or 500 more per day on average) and he has a net intake of 1590 calories today, he did not meet his calorie goal for the day. He would need to burn significantly more calories to reach his weekly weight - loss goal.

Answer:

Part A: Peter needs to burn 2090 more calories.
Part B: His new daily calorie goal should be 1900 calories.
Part C: No, Peter did not meet his calorie goal that day because his net calorie intake for the day was 1590 calories and he needs to have a net deficit of 500 calories per day on average to meet his weekly weight - loss goal.
