Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
How much would someone pay in property taxes if they live in a $329,000 home in the same area?
Answer:
$26320
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 172000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 172000.
Step 4: In the same vein, x% = 13760
Step 5: This gives us a pair of simple equations:
100% = 172000(1).
x% = 13760(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left-hand side) of both equations have the same unit (%); we have
100% / x% = 172000 / 13760
Step 7: Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
Now, I would multiply 329,000 by 8%(or 0.08) to get the answer 26320
Hope this helps!

He pays in property taxes $26320 if they live in a $329,000 home in the same area.
We have the following information available from the question is:
The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.
We have to find the how much would someone pay in property taxes?
Lets assume that:
The home worth cost is $172,000 is 100%
Let the property taxes be x
So, We equal to the value are:
$172,000 = 100%
Similarly, x% = $13,760
This gives us a pair of simple equations:
100% = $172000___(1).
x% = $13760___(2).
By simply dividing equation 1 by equation 2, we get:
100% / x% = 172000 / 13760
Taking the inverse (or reciprocal) of both sides sides
x% / 100% = 13760 / 172000
=> x = 8%
Therefore, 13760 is 8% of 172000.
They live in a $329,000 home in the same area, So
Multiply 329,000 by 8%(or 0.08)
=> 26320
