The celluloid cinema sold 150 tickets to a movie. some of these were child tickets cost $7.75 and an adult ticket cost $10.25. if the cinema sold $1470 worth of tickets, which system of equation could be used to determine how many adult tickets, a, and how many child tickets, c, were sold?

a + c = 150

7.75a + 10.25c = 1470

Step-by-step explanation:

a = adult

c = child

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: procent 54 wynosi 33,33%
