For this case we propose a system of equations:
x: Let the variable representing the number of children in the concert
y: Let the variable representing the number of adults at the concert
According to the assistance we have:
According to the cost we have:
Substituting the first in the second equation we have:
Thus, the concert was 375 adults.
On the other hand we have:
Thus, the concert was 1125 children.
In total they were:
people
ANswer:
The concert was 1500 people
Answer: 62.5%
Step-by-step explanation:
first, set up the proportion. 5/8 = ?/100 in order to solve, divide 100 by 8.
the answer is 12.5. next you multiply it by 5 to get 62.5. fill it in to your equation, and you get 5/8 = 62.5/100. turn the second fraction into a percent, then you have your answer. 62.5%
