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?

Answers

  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
