area of the parallelogram is: b x h
12 x 4 = 48 (d)
2(3) + 3(4) + 4(16) + 5(22)
Multiply
6+12+64+110
Add
192
Divide by the total amount of testers
192/((3+4+16+22))
192/45
Divide
About 4.22
Because all the scores are whole numbers, the average score is a 4

Answer: 55 performances are needed to break even.
Step-by-step explanation:
Let x represent the number of musical performances that are made.
Producing a musical costs $88,000 plus $5900 per performance. This means that the total cost of x musical performances would be
88000 + 5900x
One sold-out performance earns $7500 in revenue. If every performance sells out, it means that the total revenue would be
7500 × x = 7500x
In order to break even, total cost would be equal to total revenue. Therefore,
7500x = 88000 + 5900x
7500x - 5900x = 88000
1600x = 88000
x = 88000/1600 = 55
N - 13, because -4 and -9 are like terms
