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?

1. The equation is 6c – 55 = 455 and the regular cost of each chair is $85 ### What is the linear equation? A linear equation is defined as an equation in which the highest power of the variable is always one. Let c stands for the usual price for x chairs. So c = mx + b When a customer purchases a set of dining chairs, a one-time discount of$55 is applied to the total.
Given that a discount of $55 is applied to the total, Therefore b = -55. During the sale, Rhianna buys a set of 6 chairs and pays 455, So 6c – 55 = 455 ⇒ 6c = 510 ⇒ c = 510/6 ⇒ c = 85 Hence, the equation is 6c – 55 = 455 and the regular cost of each chair is$85
