To determine

To find: The algebraic expression that represents the number of stamps that Jake will have to put on the package.

Answer to Problem 27P

The algebraic expression is $2s+3$ .

Explanation of Solution

Given information: Jake had s stamps on the package. He doubled the number of stamps on the package and added 3 more.

Calculation:

Jake had s stamps.

He doubled the stamps on the package.
