Karen writes the algebraic expression 2s + 2.79 to represent the cost of his lunch. HE bought 2 sandwiches and a large drink. Identify any variables, coefficients, and terms in the expression. Tell what each represents

Variable:  

Coefficient: 2

Terms:   and 2.79.

Step-by-step explanation:

We have been given that Karen writes the algebraic expression to represent the cost of his lunch. He bought 2 sandwiches and a large drink. We are asked to identify any variables, coefficients, and terms in the expression.      

We know that variable is a symbol for a number that we need to figure out. Upon looking at our given expression, we can see that is a variable.

We also know that a coefficient is the number that is being multiplied with the variable. We can see that 2 is being multiplied by   , therefore, 2 is coefficient.

The terms of our given expression are and 2.79, where represents cost of 2 sandwiches and 2.79 represents cost of large drink.
