Explanation:
Answer:
20 members of the rappelling club are going on the trip
Explanation:
Total cost of the trip is $540.
If only one person goes, the cost is $540.
We can make the total number of people going x since we are not given.
Therefore, each member would pay (540/x)
We can also rep 7 with non members since the number is given as 7
Total people going= Members + non members.
Therefore, the cost per person is now (540/x+7).
Problem.
540/x -540/x +7 = 7
Multiply each with lowest common denominator.
When you expand, you get
540(x+7) - x(540)/x(x+7) =7
Simplify multiplication.
540x+3780-540x=7(x^2+7x)
Combine like terms
540x-540x+3780=7x^2+49x
3780=7x^2+49x
7x^2+49x-3780= 0
When we divide through by 7, we have
x^2+7x-540
Factorize, we have
(x^2+27x)-(20x-540)=0
x(x+27)-20(x+27)=0
(x-20)(x+27)=0
x is therefore 20 or -27
Since we know -27 cannot be a reasonable answer hence must be excluded.
The exact number of the people going on the trip is 20.
The correct answer is <span>The congo river
The congo river is so important because in its amount of flow it is only behind the Amazon and most of the river is navigable by people which makes it extremely useful in traveling from one point to another. This river is so important that it has one of the world's largest hydroelectric dams which powers a huge part of the African continent.</span>
