The movie theater sells a total of 100 tickets and makes a total of $880. If the theater charges $6 per child's ticket and $10 p
lutik1710 [3]

Answer:the number of children tickets that were sold is 30.

the number of adult tickets that were sold is 70

Step-by-step explanation:

Let x represent the number of children tickets that were sold.

Let y represent the number of adult tickets that were sold.

The movie theater sells a total of 100 tickets. This means that

x + y = 100

The theater charges $6 per child's ticket and $10 per adult's ticket. The movie theater made a total of $880. It means that

6x + 10y = 880 - - - - - - - - - - -1

Substituting x = 100 - y into equation 2, it becomes

6(100 - y) + 10y = 880

600 - 6y + 10y = 880

- 6y + 10y = 880 - 600

4y = 280

y = 280/4 = 70

x = 100 - y = 100 - 70

x = 30

The cost of renting a car is 55 a week plus.35 mile traveled during that week an equation to represent the cost would be y=55+0.
uysha [10]

Answer:

65 miles

Step-by-step explanation:

y=55+0.35x

77.75 = 55+0.35x

77.75 - 55 = 0.35x

22.75 = 0.35x

22.75 ÷ 0.35 = 0.35x ÷ 0.35

65 = x

x = 65

Elenna [48]

Answer:

Variable Y is equal to 7.5.

Step-by-step explanation:

First, open the brackets:

18 + 20y - 8 = -140

Second, subtract 18 and add 8 from/to both sides.

20y = -140 - 18 + 8

20y = -150

Third, divide by 20.
