The school concert raised $1360 from the sale of 400 tickets. If adult tickets cost $5 and student tickets $3, how many student tickets were sold?
Answers
To find the number of student tickets sold, we can use a system of equations. The number of student tickets sold is 320.
To find the number of student tickets sold, we can use a system of equations.
Let's represent the number of adult tickets sold as 'A' and the number of student tickets sold as 'S'. From the given information, we know that A + S = 400 (equation 1) and 5A + 3S = 1360 (equation 2).
We can solve this system of equations by substitution or elimination method:
Using the substitution method, we can solve equation 1 for A:
A = 400 - S
Substituting A in equation 2:
5(400 - S) + 3S = 1360
2000 - 5S + 3S = 1360
2000 - 2S = 1360
-2S = -640
S = 320
Therefore, 320 student tickets were sold.

A= adult tickets sold
S= student tickets sold
A+S=400
5A+3S=1360
-3(A+S=400)= -3A-3S=-1200 +
5A+3S=1360 =
2A = 160 so A=80
now when you plug 80 into the original equation you get 80 + S = 400 so S=320
80 Adult tickets were sold and 320 student tickets were sold.

Answer: 4000
Step-by-step explanation:
Let the number be x.
According to the given , we have the following equation:
0.9% of x = 36
Convert 0.9% into decimal number by dividing it by 100 and replace of by multiply sign, we get
Multiply 100 on both the sides , we get
Divide both the sides by 0.9 , we get
Hence, the required number is 4000.
0.009x = 36
x = 36/0.009
x = 4000

The solution to the expression (-0.75x + 6) -(2.5x -1.9) is -3.25x + 7.9
How to evaluate the expression
From the question, we have the following parameters that can be used in our computation:
(-0.75x + 6) -(2.5x -1.9)
Open teh brackets
So, we have
(-0.75x + 6) -(2.5x -1.9) = -0.75x + 6 -2.5x + 1.9
Evaluate the like terms
So, we have
(-0.75x + 6) -(2.5x -1.9) = -3.25x + 7.9
Hence, the solution is -3.25x + 7.9
