Answer:102 children and 337 adults swam at the publice pool that da
Step-by-step explanation:
let the number of children be x
and
the number of adults be y
such that the total number of people who came to use the public swimming pool be expressed as
x + y = 439----- Equation 1
and price for swimming be expressed as
1.75x + 2.50y =1021----- Equation 2
Step 2
x + y = 439----- Equation 1
1.75x + 2.50y =1021----- Equation 2
First make x the subject formulae and put in equation 2
x= 439-y
1.75 (430-y) + 2.50y = 1021
Solving gives
768.25-1.75y+2.50y=1021
2.50y-1.75y=1021-768.25
0.75y=252.75
y =252.75/0.75
y=337
To find x, put the value of y = 337 in equation 1
x+y= 439
x= 439-337
x=102
Therefore 102 children and 337 adults swam at the public pool that day
