Mr. delong's drama class is planning a field trip to see a mozart's famous opera don giovanni. tickets cost $39 each, and there are 23 students and 2 teachers going on the field trip. write and evaluate an expression to find the groups total ticket cost.

Since it was not mentioned in the problem, we can safely assume that the costs of tickets for students and teachers are just equal. Let's denote this total cost as variable x. The equation for the total cost would be:

x = 39(2) + 39(23)
x = 78 + 897
x = $975

So, the total cost of tickets for all is $975.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
