Alocal dinner theater sells adult tickets for $105 each and children’s tickets for $60 each. for a certain show, the theater sells 84 tickets for a total of $7155. how many of each type of ticket were sold?

write a system of equations that models this problem and then show all the steps to solve your system of equations using the linear combination.

The answer to your question is he sold 47 adult tickets and 37 children tickets.

Step-by-step explanation:

Data

Adult ticket = a = $105

Children ticket = c = $60

Total number of tickets = 84

Total money earn = $7155

Equations

                              a + c      = 84     (I)

                        105a + 60c = 7155 (II)

Multiply equation I by -60

                           -60a  - 60c = -5040

                          105a   + 60c = 7155

Simplify

                          45a               = 2115

                                           a = 2115 / 45

                                           a = 47 tickets

Substitute a in equation I

                          47 + c = 84

                                  c = 84 - 47

                                  c = 37 tickets

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.
