Question

On a certain hot​ summer's day, 385 people used the public swimming pool. The daily prices are $1.50 for children and $2.50 for adults. The receipts for admission totaled 792.50 How many children and how many adults swam at the public pool that​ day?

Answer 1

Answer: 215 ADULTS and 170 children swam that day!

Explanation:

c + a = 385

meaning a = 385 - c

1.50c + 2.50a = 792.50

so we can substitute it into the second formula

1.50c + 2.50(385 - c) =792.50 ---> 1.50c + 962.5 -2.50c = 792.50

c = 170 .... now we know, that 170 children went to the swimming pool.

and we still have the formula from before hence a= 215
