A skating rink changes one admission price for adults and a different admission price for children. The total admission price for a group of 4 adults and 10 children is $57. The total admission price for a group of 3 adults and 7 children is $41. What are the admission prices for an adult and for a adult?
Given:
The total admission price for a group of 4 adults and 10 children is $57.
The total admission price for a group of 3 adults and 7 children is $41.
To find:
The admission prices for an adult and for a children.
Solution:
Let the price of an adult be x and price of children be y.
According to the question,
[tex]4x+10y=57[/tex] ...(i)
[tex]3x+7y=41[/tex] ...(ii)
Multiply equation (i) by 3.
[tex]12x+30y=171[/tex] ...(iii)
Multiply equation (i) by 4.
[tex]12x+28y=164[/tex] ...(iv)
Subtract (iv) from (iii).
[tex]12x+30y-12x-28y=171-164[/tex]
[tex]2y=7[/tex]
Divide both sides by 2.
[tex]y=3.5[/tex]
Put y=3.5 in (i).
[tex]4x+10(3.5)=57[/tex]
[tex]4x+35=57[/tex]
[tex]4x=57-35[/tex]
[tex]4x=22[/tex]
Divide both sides by 4.
[tex]x=5.5[/tex]
Therefore, the price for an adult is $5.5 and price for a child is $3.5.
Rewrite y - 3 = 4(x + 2) in slope intercept form. Type in your answer without using any spaces. Example: y=-3/4x+12
Answer:
y=4x+11
Step-by-step explanation:
Answer:
y=4x+11
Step-by-step explanation:
y - 3 = 4(x + 2)
=
y - 3 =4x + 8
=
y - 3 (+3) = 4x + 8 (+3)
=
y=4x+11

There are 12 teams in the Jayhook Hockey League. Each team plays every other team twice per season, once at home and once away from home. Last season 34 of the matches played resulted in a tie. Of the others, 18 more were won by the home team than by the away team. 1: How many games did any one particular team play?
Answer:
Each team played 22 games.
Step-by-step explanation:
There are 12 teams in the league, so each team has 11 rival teams. Since each team will play against a rival team twice, that means that each team will need to play 11 x 2 = 22 games per season. Of these 22 games, 11 games will be played at home while 11 games will be played away from home.
We can calculate this by using the following formula:
Total number of games played by each team = (n - 1) x 2, where n is the total number of teams in a league.

Find 38% of 92. Round to the nearest whole number.
Answer:
38% of 92 rounded to the nearest whole number is 35.
Step-by-step explanation:
First we need to convert 38% into a decimal, 0.38.
Now we multiply 0.38 and 92.
So:
0.38 × 92 = 34.96
34.96 rounded to the nearest whole number is 35.

Kelsey's favorite crackers are available in two different sizes. The two different size boxes and their prices are shown. Crunchy Crisp Crackers Crunchy Crisp Crackers Regular Size 10 ounces Large Size 22 ounces $1.75 $3.75
Answer:
[tex]Rate = \$0.175/0z[/tex] --- Regular
[tex]Rate = \$0.1705/0z[/tex] --- Large
Step-by-step explanation:
Required (Missing from the question)
Determine the price per ounce
From the question, we have the following given parameters:
For the regular size:
Size = 10oz
Price = $1.75
For the large size:
Size = 22oz
Price = $3.75
The price per ounce is calculated using
[tex]Rate = \frac{Price}{Size}[/tex]
For the regular size:
[tex]Rate = \frac{\$1.75}{10oz}[/tex]
[tex]Rate = \$0.175/0z[/tex]
For the large size:
[tex]Rate = \frac{\$3.75}{22oz}[/tex]
[tex]Rate = \$0.1705/0z[/tex]

A local hamburger shop sold a combined total of 488 hamburgers and cheeseburgers on Friday. There were 62 fewer cheeseburgers sold than hamburgers. How
many hamburgers were sold on Friday?
9514 1404 393
Answer:
275
Step-by-step explanation:
Let h represent the number of hamburgers sold. Then the number of cheeseburgers sold is h-62, and the combined total is ...
hamburgers + cheeseburgers = combined total
h + (h -62) = 488
2h = 550 . . . . . . . . add 62, collect terms
h = 275 . . . . . . . . . .divide by 2
275 hamburgers were sold on Friday.
