Answer:
382 children and
312 adults swam
Step-by-step explanation:
Let the number of children be x
And let the number of adult be y
Hence on a hot summer day
x +y = 694 - - - - - - - 1
x= 694-y
Also the daily prices are $ 1.25 for children and $ 2.50 for adults
1.25x + 2.50y= 1257.50-------2
Let us substitute x= 694-y in equation 2
1.25(694-y) + 2.50y =1257.50
867.5-1.25y +2.50y = 1257.50
-1.25y+2.50y= 1257.58-867.5
1.25y= 390
y= 398/1.25
y= 312
Substitute y= 312 in equation 1 to find x
x + 312= 694
x= 694-312
x= 382
Hence 382 children and
312 adults swam
Answer:

Answer:
A proportional relationship
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
we have the points
(1,3) ----> ---->
(2,6) ----> ---->
(3,9) ----> ---->
(4,12) ----> ---->
(5,15) ----> ---->
therefore
The relationship between the input (x) and the output (y) represent a proportional relationship
The constant of proportionality is equal to k=3
The equation is equal to
Answer:
Rational
Step-by-step explanation:
The reason why this number is rational is because this number terminates.
