Question

examples of variables in math in real life

Answer 1

Hey ✨✨✨✨✨,

Here is your answer,⬇⬇⬇⬇

Here are some simple examples that demonstrate the relevance of algebra in the real world.

Example 1:

Going shopping

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?

We use simple algebraic formula x/y to calculate the number of bags.

x = Number of items purchased = 10

y = Capacity of 1 bag = 3

Hence,

103 = 3.33 bags ≈ 4 bags

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

Example 2:

Calculating grocery expense

You have to buy two dozen eggs priced at $10, three breads (each bread is $5), and five bottles of juice (each bottle is $8). How much money you will need to take to the grocery store?

We will use algebra to solve the problem easily and quickly.

The prices are

a = Price of two dozen eggs = $10

b = Price of one bread = $5

c = Price of one bottle of juice= $8

=> Money needed = a + 3b + 5c

=> Money needed = $10 + 3($5) + 5($8) = $10 + $15 + $40 = $65x

Hope it helps you!✔✔✔✔
