The equation used to model the regular cost of each chair at Maplewood Furniture store is given by 6c - 55 = 455
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
Let c represent the regular cost for x chairs. Hence:
c = mx + b
Given that a discount of $55 is applied to the total, hence, b = -55.
Rhianna buys a set of 6 chairs and pays 455, hence:
6c - 55 = 455
6c = 510
c = 85
The equation is given by 6c - 55 = 455 and the regular cost of each chair is $85
