Answer:
Problem 1: Concert Seating
Solution:
* Total number of rows = 24
* Number of seats per row = 18
* Total number of seats = number of rows * number of seats per row
* Total number of seats = 24 * 18 = 432 seats
Therefore, there are 432 total seats in the concert hall.
Problem 2: Book Printing
Solution:
* Number of pages per book = 320
* Number of books printed = 4,500
* Total number of pages printed = number of pages per book * number of books printed
* Total number of pages printed = 320 * 4,500 = 1,440,000 pages
Therefore, the publisher printed 1,440,000 pages.
Problem 3: High School Cafeteria
Solution:
* Number of students = 500
* Servings of fruit per student = 2
* Total servings of fruit = number of students * servings of fruit per student
* Total servings of fruit = 500 * 2 = 1000 servings
* Cost per serving = Php 15.00
* Total cost = total servings * cost per serving
* Total cost = 1000 * Php 15.00 = Php 15,000.00
Therefore, the total cost of the fruit served each day is Php 15,000.00.
Problem 4: Science Experiment
Solution:
* Number of samples = 150
* Number of chemicals per sample = 4
* Total number of chemicals = number of samples * number of chemicals per sample
* Total number of chemicals = 150 * 4 = 600 chemicals
* Cost per chemical = Php 13.50
* Total cost = total number of chemicals * cost per chemical
* Total cost = 600 * Php 13.50 = Php 8100.00
Therefore, the total cost of the chemicals needed for the experiment is Php 8100.00.
Problem 5: Landscaping
Solution:
* Length of the garden = 40 meters
* Width of the garden = 15 meters
* Area of the garden = length * width
* Area of the garden = 40 meters * 15 meters = 600 square meters
* Cost per square meter = Php 525
* Total cost = area of the garden * cost per square meter
* Total cost = 600 square meters * Php 525 = Php 315,000.00
Therefore, the total cost to plant shrubs in the entire garden is Php 315,000.00.
