Question

Can anyone show an example of how algebra can be used in real life? Thank you.

Answer 1

You purchased 10 items from a shopping plaza, and now you need plastic bags to carry them home. If each bag can hold only 3 items, how many plastic bags you will need to accommodate 10 items?

The different shapes inside the bags denote different items purchased. The number depicts the item number.

Algebra in Daily usage - Shopping Bag

We use simple algebraic formula xyxy to calculate the number of bags.

x = Number of items purchased = 10

y = Capacity of 1 bag = 3

Hence,

103103 = 3.333.33 bags ≈ 44 bags

So,we need 4 shopping bags to put 10 items.
