Answer 1

Variable:
`s`

Coefficient: 2

Terms:
`2s` and 2.79.

Explanation:

We have been given that Karen writes the algebraic expression
`2s+2.79` 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
`s` 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
`s` , therefore, 2 is coefficient.

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