Question

On a certain hot​ summer's day, 459 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $847.00. How many children and how many adults swam at the public pool that​ day?

Answer 1

let there be x children and (481-x) adults.

1.25x +2.25(481-x) = 865.25

1.25x +1082.25 -2.25x =865.25

x= 217

so 217 children and 481-217 = 264 adults
