Question

On a certain hot summer’s day, 710 people used the public swimming pool. The daily prices are $1.25 for children and 2.50 for adults. The receipts admission totaled $1288.75. How many children and how many adults swam at the public pool that day?

Answer 1

CHILDREN= 389

ADULT=310

Explanation:

1) A + C = 710 2) A*2.50 + C*1.2 = 1288.75

OR, A= 710-C (710-C)*2.50 + C*1.2=1288.75

1775-2.50*C+1.25*C=1288.75

1775 -1.25*C = 1288.75

-1.25*C=1288.75-1775

1.25*C=486.25

C = 486.25/1.25

C = 389

Again or, A + C = 710

A = 710 - C

A = 710 - 389

A = 321
