Uses of algebra in real world
1. Distribution of items in covers while shopping. A simple example is you purchase 20 items and a carry bag can hold only 4 items. Here we can use the formula x/y where x is the items purchased and y is the number of items a bag can hold
20/4 = 5
2. Calculation of expenses in a shopping bill
Suppose I purchase 3 items of different quantity 5 apples, 10 eggs and 5 milk packets
1 apple = a = Rs 10
1 egg = b = Rs 5
1 milk packet = c = Rs 20
Total price = 5a + 10b + 5c
= 5(10) + 10(5) + 5(20)
= 50 + 50 + 100
= 200
3. Filling the petrol tank of your bike
You have 200 Rs and each litre of petrol costs Rs 100. So by using the formula x/y which is Total amount available/Price per litre, we will get to know how many litres of petrol we can fill
200/100 = 2 litres
4. Theatre bill
A group of 4 friends visit a theatre where the ticket cost is 100 per person and food expensed are 200 per person and travel expenses are 50 per person. What will be the total cost spent by all of them
4a + 4b + 4c = total cost spent
a – Ticket cost
b – Food cost
c – travel cost
4(100) + 4(200) + 4(50) = total cost
400 + 800 + 200
Total amount spent = 1400
5. Travel time
I need to travel 200 km and I travel at a speed of 40 km per hour. How much time is needed to complete my journey?
x/y = Distance needed to travel/Distance travelled per hour
= 200/40 = 5 hours
6. Estimation of weekly budget
7. Creating a time table for scheduling day to day activities.
