Answer:
its the last one
Step-by-step explanation:
Answer:
8 people in the original group.
Step-by-step explanation:
Let x be the number of people who were originally present for the dinner that cost $160. Their average cost per person would be:
$160/x
If 2 more people join, there are x+2 people. Ignoring the awkward situation that they apparently did not order any additional food, they agree to share the cost of the dinner. The average cost is now:
$160/(x+2)
We are told that this new average is now $4 less per person.
$160/(x+2) = ($160/x) - $4
$160 = (($160/x) - $4)(x+2)
x = 8 people
??? Where’s the rest of that problem
We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.
There are about 2 pounds in one kilogram.
Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.
2 * 2 = 4
So, the answer to this question is 4 pounds.
