Question

Maplewood Furniture Store is having a sale on dining room furniture. When a customer purchases a set of dining chairs, a one-time discount of $55 is applied to the total. During the sale, Rhianna buys a set of 6 chairs that match the table she inherited from her grandmother. Rhianna pays $455 in all.
Which equation can you use to find the regular cost, c, of each chair? What is the regular cost of each chair

Answer 1

Let c be the regular cost (in dollars) of each chair. The sale price is 6c minus the $55 discount, which equals $455:

6c − 55 = 455

Solve: 6c = 510, so c = 85.

Each chair regularly costs $85.
