Answer:
10 bags for $5.49
Step-by-step explanation:
4 bags for $2.39 = 1 bag for $0.5975
10 bags for $5.49 = 1 bag for $0.549
Here you have 2 linear equations and are to solve this system. Both equations have already been solved for y, so you can set one of them = to the other one:
-2x+11 = -3x+21.
Then 3x-2x = 21 - 11, or x = 10 (answer)
Find y by subst. x = 10 into either of the given equations.
Solution is then (10, ? )
10 n = C
Finding the total would simply be multiplying the cost of the tickets by number of students.
