The number of teachers is 4 and number of students is 10 on the trips if the tickets were $22.00 each for teachers and $8.50 each for students.
<h3>What is linear equation?</h3>It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
In Maths museum tickets were $22.00 each for teachers and $8.50 each for students, and the group paid $173.00 in total.
Let's suppose the number of teachers is x and number of students is y
22x + 8.5y = 173 ...(1)
5.5x + 2y = 42 ...(2)
After solving the above equation by substitution method we get;
From equation (1):
Multiply by 2 with equation (1)
y = 10
x = 4
Thus, the number of teachers is 4 and number of students is 10 on the trips if the tickets were $22.00 each for teachers and $8.50 each for students.
