Answer:
7th graders- 100 students
8th graders- 110 students
Step-by-step explanation:
Let the number of 8th graders be represented by x and 7th graders be represented by y
<u>Equation based on number</u>
There difference between 8th and 7th graders is 10 hence equation becomes
x-y=10
<u>Equation based on contribution</u>
While x contribute each $8 and y contribute each $5, the total contribution is $1380 hence the equation becomes
8x+5y=1380
<u>Combining equations</u>
Having the two simultaneous equations which are
x-y=10
8x+5y=1380
Solving the equations.
5x-5y=50
8x+5y=1380
------------------
13x=1430
x=1430/13=110
Therefore, 8th graders are 110. Since the 8th graders were 10 more than 7th graders, the 7th graders will be 110-10=100 students
Answer:
Parabola
Step-by-step explanation:
The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.
