Tickets to We Didn't Lose the Game; We Just Ran Out of Time, a brand-new documentary about
coaches who lost in Super Bowls, cost only $3.50 for adults and $1 for children. If 38 people attended
the premiere and the theatre sold $110.50 worth of tickets

29 adults and 9 children attended the premiere.

Step-by-step explanation:

You didn't say what you're expected to calculate but based on the question, I'll help you calculate the number of children and adults that attended the premiere.

Let adults be represented by a

Let the children be represented by c.

38 people attended the premiere. This can be written as:

a + c = 38 equation i

Tickets cost $3.50 for adults and $1 for children and the theatre sold $110.50 worth of tickets. This can be written as:

3.50a + c = 110.50 equation ii

Combining both equations together

a + c = 38 i

3.50a + c = 110.50 ii

Subtract equation ii from equation I

-2.5a = 72.5

2.5a = 72.5

a = 72.5/2.5

a = 29

Recall that a + c = 38

c = 38 - 29

c = 9

29 adults and 9 children attended the premiere.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
