Each time you fold a paper it will double the amount of parts. When you think about it, it's just multiplying by 2 a bunch of times.
One fold is 2 times 1, which is 2.
The second fold is 2 times 2, which is 4.
The third fold is 4 times 2, which is 8.
Using this process, we can simplify that into exponents. If the amount of times you fold is x and the parts double for each fold, then the amount of parts can be represented by:

So if the amount of parts is given and we need the amount of folds, just keep doubling until you get to 64. The amount of times you doubled is the number of times Sylvie folded.
Later you will learn that the opposite of an exponent is a logarithm, which would look like this:

But don't worry about that yet.
Answer:
994.5
Step-by-step explanation:
First, you need to figure out how many people are actually attending the event. It says that there are 50% more so we are going to have to add 56% of 150 to 150.
150 x 0.56 = 84
150 + 84 = 234
Now, we have to multiply this by 4.25, because this is the cost of the food per person.
234 x 4.25 = 994.5
The square root of 147 when rounded to the nearest tenth is about 12.1
