1 answer:
Answer:
<u>There were 257 children and 365 adults at the public pool.</u>
Step-by-step explanation:
Let the number of children and adult be x and y respectively,
x+y = 622
1.5x+2y = 1115
Now,
x+y = 622
or, x = 622 - y
Now,
1.5x + 2y= 1115
or, 1.5(622-y) + 2y = 1115
or, 933 - 1.5y + 2y = 1115
or, 933 + 0.5y = 1115
or, 0.5y = 1115-933
or, 0.5y = 182
so, y = 182/0.5
so, y = 365
Now,
x+y = 622
or, x + 365 = 622
so, x = 257
