A group of 41 teachers went to Disneyland. A regular ticket cost $113. The senior rate is $109. If the total admission price was $4561, how many teachers got the senior rate?

23 teachers got the senior rate

Step-by-step explanation:

Let x represent the number of teachers that got regular tickets.

Let y represent the number of teachers that got senior rate.

.A group of 41 teachers went to Disneyland. It means that

x + y = 41

A regular ticket cost $113. The senior rate is $109. If the total admission price was $4561, it means that

113x + 109y = 4561- -- - - - - - - - -:- -1

Substituting x = 41 - y into equation 1, it becomes

113(41 - y) + 109y = 4561.

4633 - 113y + 109y = 4561.

- 113y + 109y = 4561 - 4633

- 4x = - 72

x = - 72 / - 4

x = 18

y = 41 - y = 41 - 18

y = 23

4 + 5 7/9= 9 7/9

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
