Marisol sells wedding cakes. She charges a flat fee of $245 to make the wedding cake, plus an additional $120 per tier of cake. What linear equation can be used to graph the price (y) of one of Marisol's wedding cakes?

120x + 245 = y

x = number of additional tiers

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

i believe the answer is the polygon, heptagon.
