What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that the cost of a hamburger and a soft drink together is $2.10. The cost of 2 hamburgers and a soft drink together is $3.50.

The cost of a soft drink is calculated by making two equations.

h + s = $2.1     ..................................( 1 )

2h + s = $3.5  .................................( 2 )

Here, h = hamburger and s = soft drink.

Subtract equation ( 1 ) from equation ( 2 ).

2h - h = $3.5 - $ 2.1

h = $1.4

Hence, the cost of a soft drink is $1.4. Hence, option D is correct.
