On a certain hot summers, 256 people used the public swimming pool. The daily prices are $1.75 for children and $2.75 fo adults. The receipts for admission totaled to $551.50. How many children and adults swam that day? Explain.

152 children and 104 adults swam.

Step-by-step explanation:

Let x represent the number of children tickets. It also means that x children swam.

Let y represent the number of adult tickets. It also means that y adults swam.

On a certain hot summers, 256 people used the public swimming pool. This means that

x + y = 256

The daily prices are $1.75 for children and $2.75 for adults. The receipts for admission totaled to $551.50. This means that

1.75x + 2.75y = 551.5- - - - - -- - - - - -1

Substituting x = 256 - y into equation 1, it becomes

1.75(256 - y) + 2.75y = 551.5

448 - 1.75y + 2.75y = 551.5

- 1.75y + 2.75y = 551.5 - 448

y = 103.5

Approximately 104 adults

x = 256 - y = 256 - 104

x = 152

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
