HELP w/ question!!!!?

Question

i am really confused by this question. how do i solve it?? can u tell me step by step if u can

The best selling dessert at Chez Russell earns revenue of $5000 per week. During Restaurant Week, they are required to give a 10% discount on this dessert. Because the owner is a crook, he decides to mark up the price the week before Restaurant Week and then give the 10% discount off the marked up price. During the marked up week, they still sold the same amount of pieces as any prior week. However, they expect to sell 100 more pieces during restaurant week. If the revenue from this dessert is the same for the marked up week and restaurant week, what is the normal price of the dessert, rounded to the nearest cent?

Answer 1

You need to use simultaneous equations to solve this problem. Here's how to set it up:

revenue - $5000
regular price = X
number sold at regular price= Y
mark up price = X + markup
Revenue during normal week = X times Y = $5000
Revenue during Mark up week = (X + mark up) times Y
Number sold during restaurant week = Y +100
Revenue during restaurant week = (markup price - 10%) times (Y + 100)

solve this equation from the info above:

Revenue markup week = revenue restaurant week
