A group of middle school students were randomly chosen and asked about whether or not they will attend the school dance. Of these students, 65% said yes, they will attend. If 52 students responded yes, how many students were surveyed?

80 Students were surveyed.

Step-by-step explanation:

To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.

1. I know that a 65% of students are 52 students. I need to know how many students represent that 100%.

2. So if 52 students mean 65%

             X students mean   100%

Pay attention here. We have to put the same elements in the same columns. Students with studients and percentage with percentage.

3. Now I have to cross these details. I have to multiple 52*100. So:

52*100= 5200

4. Then divide that result by 65.

5200/65= 80

5. So 80 is the total number of students surveyed.

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
