Answer: could you make the question a little clearer
Step-by-step explanation:
Multiply the average by the number of tests to find the total of the scores:
82 x 3 = 246
88 x 3 = 264
The total of the three tests would need to be between 246 and 264
The total of the first two tests is 79 + 85 = 164
Subtract the total of the first two from the totals above:
246 - 164 = 82
264 - 164 = 100
The score of the third test needs to be between 82 and 100
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600
