Plz hurry and show your work thanks :)
The cost of admission to the state aquarium increased from $12.50 to $15.00. What was the percent increase?
A project is underway to increase the size of the parking lot at the library. Once the project is completed, there will be 24 additional parking spots. This represents a 40% increase in the number of parking spots. How many parking spots will there be once the project is completed?
There are 29 women and 19 men on a bus. If 25% of the riders get off at the first stop, how many people will be left on the bus?
To find the percent increase, you can use the formula:
Percent Increase = (New Value - Original Value) / Original Value * 100
Let's plug in the given values:
New Value = $15.00
Original Value = $12.50
Percent Increase = (15.00 - 12.50) / 12.50 * 100
= 2.50 / 12.50 * 100
= 0.2 * 100
= 20%
Therefore, the cost of admission to the state aquarium increased by 20%.
To find the total number of parking spots, we can use the formula:
Total Number of Parking Spots = Original Number of Parking Spots + (Original Number of Parking Spots * Percent Increase)
Let's plug in the given values:
Original Number of Parking Spots = 0 (since it is not provided in the question)
Percent Increase = 40%
Total Number of Parking Spots = 0 + (0 * 0.40)
= 0 + 0
= 0
Therefore, once the project is completed, there will still be 0 parking spots.
To find how many people will be left on the bus, we can use the formula:
Number of People Left on the Bus = Total Number of People - Number of People Getting Off
Let's plug in the given values:
Total Number of People = 29 women + 19 men = 48 people
Number of People Getting Off = 25% of 48 = 0.25 * 48 = 12 people
Number of People Left on the Bus = 48 - 12 = 36 people
Therefore, there will be 36 people left on the bus.
