You sell tickets for admission school play and collect a total of $21. admission prices are $3 and children prices are $2 for children. you sold 8 tickets. how many adult tickets and how many children tickets did you sell? make a table of # of tickets and total cost. make their equations and graph them its confusing for me. can you me?

Adult: 5

Kids: 3

Step-by-step explanation:

In order to find the answer to this problem, we had to think of products of 3.

I first though of 6*3. This would be 18. But we cannot evenly put the children's tickets in that.

Next I did 3*5. This is 15. I tried adding 2 multiple times to get to 21.

17,19,21! I knew that is must be 5 and 3.

I hope I explained this enough. If you still don't get it, ask me another question. :)

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
