Ashleys class bought 3 bags of bird sees and a bird feeder for their class garden area. The bird feeder cost $27. Write an expression that can be used to find the total cost.

27 + 3b =

To find the total cost, we need to add the cost of the bird feeder to the cost of the bird seeds. Let's represent the cost of each bag of bird seeds as "x" since it is not specified in the question.

The total cost can be calculated using the expression:

Total cost = Cost of bird feeder + Cost of bird seeds

Total cost = $27 + (3 * x)

Therefore, the expression that can be used to find the total cost is $27 + (3 * x).

Please note that "x" represents the cost of each bag of bird seeds, which is not given in the question.
