Step-by-step explanation:
Total students were 500.
We define our grupes:
Rock = A
country = B
Jazz = C
The groups are given by,
A=192
B=156
C=118
From the combination we have:
Students who liked Rock only are:
Those numbers are considered composite
Since, by definition, , we deduce that
So, we have
The total cost of these pepperoni slices is $1.92
<h3>
What is the total cost of these pepperoni slices?</h3>
Each slice measures 7/8 of an inch. Here we have N slices, such that the measure of the N slices is 56 inches, then we have:
N*(7/8 in) = 56 in
Now we can find the value of N, the number of slices used:
N = (8/7)*56 = 64
And each slice costs $0.03, then the cost of the 64 slices is:
C = $0.03*64 = $1.92
The total cost of these pepperoni slices is $1.92
