Swimming Pool On a certain hot summer's day, 691 people used the public swimming pool. The daily prices are $1.75 for children and $2.00 for adults. The receipts for admission totaled $1295.50.
How many children and how many adults swam at the public pool that day?

Number of children= 346

Number of adults= 345

Step-by-step explanation:

We can set up a system of equations to solve for the number of children and adults.

x= number of children

y= number of adults

We know that the total number of people at the swimming pool is 691, which is comprised of both children and adults. We can write this equation as...

x+y=691

We also know that children pay 1.75 dollars and adults pay 2 dollars, with a total of 1295.50 dollars.

1.75x+2y=1295.50

We can now solve the system with elimination by multiplying the first equation by negative 2.

x+y=691 -> -2x-2y= -1382

-2x-2y= -1382

1.75x+2y=1295.50

-0.25x=-86.5

x= 346

Now that we found the number of children, we can solve for the number of adults.

x+y=691

346+y=691

y= 345

the answer is c

step-by-step explanation:

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
