At school Spencer is selling tickets to the Little Mermaid play. The first day of ticket sales sold 5 senior citizen tickets and 4 child tickets for a total of $22. The school took in $54 with 24 senior citizen tickets and 2 child tickets. Create a system of equations based on the problems and find the cost of child tickets and senior tickets.

Step-by-step explanation:

Let A be cost of adult ticket

Let C be cost of child ticket

5A + 4C = 22

A = (22 - 4C)/5

                24A + 2C = 54

24((22 - 4C)/5) + 2C = 54

 105.6 - 19.2C + 2C = 54

                     - 17.2C = - 51.6

                            C = $3.00

A = (22 - 4(3))/5 = $2.00

Step-by-step explanation:

Let,

Senior tickets = x

Child tickets = y

In case 1

5x + 4y = 22 (1)

In case 2

24x + 2y = 54

On multiplying both sides by 2

48x + 4y = 108 (2)

On subtracting 1 and 2

48x + 4y - (5x + 4y) = 108 - 22

48x + 4y - 5x - 4y = 86

43x = 86

x = 86/43

x = 2

From 1

5(2) + 4y = 22

10 + 4y = 22

4y = 22 - 10

4y = 12

y = 12/4

y = 3

Hence,

Cost of 1 child ticket = $ 2

Cost of 1 adult ticket = $ 3

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
