Give the step-by-step reasoning process and then the final answer. Hannah is at a restaurant. She spends $23 in total on an entree and a dessert. If the entree costs $5 more than the dessert, how much does the entree cost, in dollars?
User
Let D be the cost of the dessert in dollars. The entree costs D + 5 dollars. D + (D + 5) = 23. 2D + 5 = 23. 2D = 18. D = 9. The entree costs $14.
The final answer: 14.
