A.
Guess and test. 

Guess that Emily spent $30. Multiply $3.99 by 2. Then add that answer to $14.99. Divide this number by 5. If the answer is not 30, then revise your guess, and test your answer again.

B.
Work backward. 

Start by multiplying $3.99 by 2 to find the cost of the lights. Add the cost of the wreath to the sum and then divide by 5.
