We are asked to make an algebraic expression for the given situation. The key phrase is ... added to ... This tells us that we should add two things.
... + ...
The two terms that we are adding together are p pennies and 22 pennies. Since a number comes first in the statement, it should be on the left-hand side of the addition.
p pennies + 22 pennies
When we say pennies, this tells us that the value of our expression should be measured in pennies. Let's remove this word from the statement as it does not change how the expression should be written — only how we should understand it.
p pennies added to 22 pennies
p + 22
Note that this is only one of multiple ways to algebraically express the given statement.
