Swimming Pool On a certain hot summer's day, 356 people used the public swimming pool. The
daily prices are $1.75 for children and $2.25 for adults. The receipts for admission totaled
$666.00. How many children and how many adults swam at the public pool that day?
~~~~~~~~~~~~~~~
Let x = # of adult tickets;
then the number of children tickets is (356-x).
Write the total money equation (revenue equation)
1.75*(356-x) + 2.25x = 666 dollars.
From the equation
x = = 86.
ANSWER. 86 adults and 356-86 = 270 children.
CHECK. 86*2.25 + 270*1.75 = 666 dollars. ! Correct !
Solved.
