Beth bought 20 tickets to a movie, where adult tickets cost $8.00 and senior citizen tickets cost $4.00. She spent a total of $1

olchik [2.2K]

Answer:

The Total number of adults ticket's is 15

The Total number of Senior citizen ticket's is 5

Step-by-step explanation:

Given as :

The total number of movies tickets were bought = 20

The cost of adults tickets = $ 8.00

The cost of senior citizen tickets = $ 4.00

The total money spent on movie tickets = $ 140

Let The total number of adults tickets = A

And The total number of senior citizen tickets = S

Now, According to question

The total number of movies tickets were bought = 20

I.e The total number of adults tickets + The total number of senior citizen tickets = 20

Or, A + S = 20

And $ 8 A + $ 4 S = $ 140 .........1

I.e 8 × ( A + S ) = 8 × 20

Or, 8 A + 8 S = 160 .......2

Solving the equation 1 and 2

Or, ( 8 A + 8 S ) - ( 8 A + 4 S ) = 160 - 140

Or, ( 8 A - 8 A ) + ( 8 S - 4 S ) = 20

or, 0 + 4 S = 20

∴ S = $\frac{20}{4}$

I.e S = 5

So, The number of Senior citizen ticket's = 5

Put The value of S in eq 1

So, 8 A + 4 × 5 = 140

Or, 8 A = 140 - 20

Or, 8 A = 120

∴ A = $\frac{120}{8}$

I.e A = 15

So, The number of adult's tickets = 15

Hence The Total number of adults ticket's is 15

And The Total number of Senior citizen ticket's is 5 Answer

Rama09 [41]

Answer:

x = 8

Step-by-step explanation:

Let there are x friends.

The tickets cost $24.50 and the refreshments for each friend were $2.50 and $4.85 each.

Total cost = $83.30

We need to solve for x. The equation for the scenario is given by :

$2.50x + $4.85x + $24.50 = $83.30

Taking like terms together

$2.50x + $4.85x = $83.30-$24.50

7.35 x = 58.8

x = 8

So, there are 8 friends.

Strike441 [17]

Well, youlook at the ratio and see that it is 3-6, total out of 9 flowers: 3pink and 6blue. You divide 72 by 9 to put it in the context of the ratio and get 8. Next you multiply 8 by 3, and you get 24/72 flowers are pink.

3+6=9, 9/72=8, 8*3=24 pink, 24/72 flowers are pink
