Answer:
$14.8
Step-by-step explanation:
There is a mistype in the question. It should say: ... <em>si cada uno de ellos hicieron una contribución de </em><em>dieciseis</em><em> pesos...</em>
So if everybody contributes $14, they make a total of 14*x, where x denotes the number of students. In this scenario, $4 are left, calling y to the cost of the trip, then:
14*x = y - 4 (eq. 1)
In the other scenario, everybody contributes $16 and $6 are in excess, so
16*x = y + 6 (eq. 2)
subtracting eq. 1 to eq. 2:
16*x - 14*x = y + 6 - (y - 4)
2*x = y + 6 - y + 4
2*x = 10
x = 10/2 = 5
Replacing this value in eq. 1:
14*5 = y - 4
70 + 4 = y
y = $74
If every student pays: 74/5 = $14.8, then they would get altogether the exact cost of the trip
3(x+6)=-24
Divide both sides by 3
3(x+6)/3=-24/3
X+6=-8
X=-14
Answer: 500 g of candy in each bowl
Step-by-step explanation:
1,000 g = 1Kg
4,500 g - 1,000 g = 3,500 g of candy were divided over 7 bowls:
Each bowl contains = 3,500 g➗7 bowls = 500 g candy/bowl
Answer: 500 g of candy in each bowl

I’m thinking your r in the first equation is actually an x.
X + 2(2x -4) =10
X +4x -8 =10
5x = 18
