That's the formula you use if you know a temperature in Celsius and
you want to know what the Fahrenheit equivalent is.
If the Celsius temperature is 5, then the formula says that
F = (9/5)(5) + 32 =
(9) + 32 = <em>41 degrees Fahrenheit</em>.
Restaurant 1 : y = 7k + 39
restaurant 2 : y = 2k + 44
7k + 39 = 2k + 44
7k - 2k = 44 - 39
5k = 5
k = 5/5
k = 1
y = 2k + 44
y = 2(1) + 44
y = 2 + 44
y = 46
Dinner would cost $ 46 at either restaurant if Lina's lobster weighed 1 kilogram.
Using the Fundamental Counting Theorem, there are 240 ways to choose general education courses from these 4 areas.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

Considering the number of options for each course, the parameters are given as follows:
.
Hence the number of ways is given by:
N = 5 x 4 x 4 x 3 = 240.

It’s 1/2 because every time the x variable goes up 1, the y variable goes up 2
