## Algebra real world problems

Introduction :

Algebra is a sub class of mathematics. Algebra plays the vital role in our day today life. To algebra word review, we want to know the following four basic operations such as addition, subtraction, multiplication and division and also associated with the following important terms such as variables, constant, coefficients, exponents, terms and expressions. Also to algebra word problems review, we want to put symbols and alphabets for the unknown values to create a statement. Hence, algebra real world problems may be caused as an extension of Arithmetic.

There are 25 passengers in a deluxe bus and 20 passengers in an Ordinary bus. How many passengers is there altogether in the two Buses?

Passengers in a Deluxe Bus = 25

Passengers in an Ordinary Bus = 20

Total number of passengers in altogether of Buses = in a deluxe bus + in an ordinary bus

Hence, 25 + 20 = 45

A Butcher had 158 pounds of meat in his shop. He sold 127 pounds of meat. How much pounds did he have left?

The total pound of meat = 158 pounds.

Sold pounds of meat = 127 pounds

So, 158 – 127 = 31

In a basket, there are 18 potatoes in each basket. How many potatoes are there in 5 baskets?

So, 19 × 5 = 95

There are 95 potatoes in 5 baskets.

Peter bought a sack of 90 kg of brown sugar to prepare bake items. He has packed the brown sugar equally into the 5 bags. How many kilograms of brown sugar were there in each bag?

**Example problems in algebra real world problems:****Example 1:**There are 25 passengers in a deluxe bus and 20 passengers in an Ordinary bus. How many passengers is there altogether in the two Buses?

**Solution:**Passengers in a Deluxe Bus = 25

Passengers in an Ordinary Bus = 20

Total number of passengers in altogether of Buses = in a deluxe bus + in an ordinary bus

Hence, 25 + 20 = 45

**Answer**is 45 passengers in both the buses.**Example 2:**A Butcher had 158 pounds of meat in his shop. He sold 127 pounds of meat. How much pounds did he have left?

**Solution:**The total pound of meat = 158 pounds.

Sold pounds of meat = 127 pounds

Remaining pound of meat =?

So, 158 – 127 = 31

**Answer**is 31 pounds of meat has left.**Example 3:**In a basket, there are 18 potatoes in each basket. How many potatoes are there in 5 baskets?

**Solution:**So, 19 × 5 = 95

There are 95 potatoes in 5 baskets.

**Example 4:**Peter bought a sack of 90 kg of brown sugar to prepare bake items. He has packed the brown sugar equally into the 5 bags. How many kilograms of brown sugar were there in each bag?

**Solution:**90 ÷ 5 = 18

There were 18 kg of brown sugar in each bag.
