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?

Respuesta :

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
