At the movie theatre, child admission is $6.20 and adult admission is $9.50. on monday, three times as many adult tickets as child tickets were sold, for a total sales of $1214.50. how many child tickets were sold that day?

C = 35 //number of child tickets sold that day

Step-by-step explanation:

Child admission ticket: $6.20

Adult admission ticket: $9.50

Total sales = $1214.50

The statement "Three times as many adult tickets as child tickets were sold:" is translated as:

Number of adults tickets = A

Number of child tickets = C

A = 3C

Sale of total tickets = $1214

9.5A + 6.20C = 1214

put NA = 3NC

3C(9.50) + 6.20C = 1214

28.5C + 6.20C = 1214

34.7C = 1214

C = 35 //number of child tickets sold that day

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
