Answer: 12 child tickets
Step-by-step explanation:
We can use system of equations to find how many child tickets were sold. Let's say x is adult and y is child.
Equation 1
5.25x+3.05y=498.6
This equation comes from the cost of tickets.
Equation 2
x+y=100
This equation comes from the number of tickets.
We can use elimination method to solve for y.
5.25x+3.05y=498.6
5.25x+5.25y=525
Now, we can subtract the equations for x to cancel out and to solve for y.
-2.2y=-26.4
y=12
Answer:
30 waiters
Step-by-step explanation:
the ratio of 5 waiters to 2 cooks
you are given the total number of waiters and cooks = 42
write equation
x (5 + 2) = 42
7x = 42
x = 6
now distribute the x into waiters which is 5x or 5(6) = 30 waiters
additionally 2x is for cooks or 2(6) = 12 cooks; which adds up to 42
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
