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?
Let the regular cost of each chair be c.
Since Rhianna receives a one-time discount of $55 on the total, the total cost of the chairs after the discount is (6c - 55).
Rhianna pays $455 in all, therefore, we can set up the equation:
6c - 55 = 455
