Isabella is going to a carnival that has games and rides. Each game costs $2 and each ride costs $4. Isabella spent $40 altogether on 15 games and rides. Graphically solve a system of equations in order to determine the number of games Isabella played, x, and the number of rides Isabella went on, y.

 (10,5)

Step-by-step explanation:

You have to graph it but the equations are

x+y=15 (total number of games and rides)

2x+4y+40 (total money spent)

first equation is also y= -x+15

second is 4y= -2x+40

                 y= -.5x+10

So graph y= -x+15 and y= -1/2x+10 and where the lines cross is your answer

also -x+15= -.5x+10

           15=.5x+10

           5=.5x

           10=x

10+y=15

y=5

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
