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.

The number of years to the nearest hundredth is t = 21 years and 3 months.
<h3>What is compound interest?</h3>It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
It is given that:
A = $25,600
P = $29,00
r = 10.4 = 0.104
n = 4
After solving:
t = 21.212 years
Or
t = 21 years and 3 months
Thus, the number of years to the nearest hundredth is t = 21 years and 3 months.
