At a carnival, 700 tickets were sold for a total
Diano4ka-milaya [45]

Answer:

The adult tickets are <u>400</u> and the children tickets are <u>300</u>.

Step-by-step explanation:

Given:

At a carnival, 700 tickets were sold for a total  amount of $5500. An adult ticket cost $10   and a children's ticket cost $5.

Now, to find the  number of adult tickets and the number of  children's tickets sold.

<em>Let the number of adult tickets be </em>x.<em />

<em>And let the number of children tickets be </em>y.<em />

So, the total number of tickets sold:

x+y=700\\\\y=700-x\ \ \ ....(1)

Now, the total amount of tickets:

x(10)+y(5)=5500

Substituting the value of y from equation (1):

x(10)+(700-x)(5)=5500\\\\10x+3500-5x=5500\\\\5x+3500=5500

<em>Subtracting both sides by 3500 we get:</em>

<em />5x=2000<em />

<em>Dividing boths sides by 5 we get:</em>

x=400.<u />

<u>The number of adult tickets = 400.</u>

Now, substituting the value of x in equation (1) we get:

y=700-x\\\\y=700-400\\\\y=300.

<u>The number of children tickets = 300.</u>

Therefore, the adult tickets are 400 and the children tickets are 300.

Zoe is working two summer jobs, making $7 per hour babysitting and making $15 per
Rasek [7]

Answer:

7, 8, 9, 10

Step-by-step explanation:

If Zoe worked 4 hours of babysitting at $7 per hour, she earned $28. Therefore, she must earn another $102 to earn at least $130. At $15 per hour, she must work a minimum of 7 hours clearing tables to make at least $102. This is fine since she can work another 10 hours before reaching her maximum of 14 total hours. Therefore, all possible values for the number of whole hours clearing tables that she must work to meet her requirements are 7, 8, 9, 10.
