Answer:
1800yearbook(D)
Step-by-step explanation:
Cost of printing a year book = $5
A year book is sold at $15
The profit on each year book = $15 - $5 = $10
Let y represent the number of year books sold for a break even to occur.
A break even occurs when the amount sold is equals the amount invested
10y = 18000
y = 18000/10
y = 1800 yearbooks
Answer:

The temperature decreases from 21°C to 17°C.
We need to find the percentage decrease in the value of temperatures.
The percentage decrease in any value is given by :

Formula for the area of a circle: A = pi x r^2
We are given the diameter in this problem, but we need the radius. To find the radius, we will need to divide the diameter by 2.
8 / 2 = 4
A = pi x 4^2
A = pi x 16
A = 16pi cm^2
Hope this helps!! :)
There are 163 people going to the movies 5, 6 or 7 times per month
there are 133 people going more than 7 times
So in total, there are 163+133=196 people going to the movies at least 5 times a month.
In total there are 728 people in the experiment.
P(a person goes at least 5 times per month)=n(people going at least 5 times)/n(people in the experiment)
= 196/728=0.269
