The answer is option (C).
What is a percentage?
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The percentagechange is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
To find the number of people who rode the roller coaster,
We can multiply the total number of people at the park by the percentage who rode the roller coaster:
So,
The number of people who rode the roller coaster.
= 77% × 1,200
= 77/100 x 1200
= 924
Therefore,
924 people rode the rollercoaster.

Answer:
1/4
Step-by-step explanation:
Okay so there are 4 different colors and you are spinning it 100 times.
Green is one of the for colors so the probability is 1/4
but the denominator for now must be 100
What is 1/4 of 100 ?
25.
So the probabiltiy is 25/100 but you need to reduce so it would be 1/4

The percentage increase in team sales is 44% and this can be determined by using the unitary method.
Given :
The sales increase from 90 units to 130 units.
The following steps can be used in order to determine the percentage increase in sales:
Step 1 - The unitary method can be used in order to determine the percentage increase in sales.
Step 2 - According to the given data, the team sales are 90 units which are 100%. After increasing the sales becomes 130 units.
Step 3 - So, let the percentage of 130 units be 'x'. So, the value of 'x' is:
Step 4 - So, the percentage increase in sales is:
The percentage increase in team sales is 44%.
For more information, refer to the link given below:
The sales was increased by 44.4%.
Step-by-step explanation:
- Lets do this cumulative
- 90 of 10 % = 9 which is 99
- 90 of 10 % = 9 which is 108
- 90 of 10% = 9 which is 117
- 90 of 10% = 9 which is 126
- 90 of 4 % = 3.6 which is 129.6
- 90 of 0.044% = 0.0396 which is 129.99
- This comes to nearly 44.44 to be closer there was an increase.
- Always rule 1 approximation use 50% of 90 if it is above 130.
- Down it to 40% of 90 see if the sales is lower than 130.
- It should always start with 50,40,30....10 percents.
- Alternative should be 10,1 or decimals.
- Approximation using decimals rounding up becomes simple.
