On a certain hot summer day, 431 people used the public swimming pool. The daily prices are 1.50 for children and 2.00 for adults. The receipts for admission totaled to $825.50. How many children and how many adults swam at the public pool that day?

the no of children and no of adults swam that day is 73 and 358 respectively

Step-by-step explanation:

Let us assume the no of children and no of adults swam that day be x and y

Now as per the question

The following equations are

x + y = 431

we can write as

x = 431 - y

1.50x + 2y = $825.50

1.50(431 - y) + 2y = $825.50

646.50 - 1.50y + 2y = 825.50

0.5y = 179

y = 358

And x = 431 - 358

= 73

Hence, the no of children and no of adults swam that day is 73 and 358 respectively

-1, -2, -3, -4, -6
