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

(edited to be in the proper order)

So for this, you will be using the exponential equation formula, which is y=ab^x , with a = initial value and b = growth/decay.

Since we start out with 855, that is your a variable.

And since this is a growth by 6%, add 1 and 0.06 (6% in decimal form) together, which is 1.06. That is your b variable.

In this case, time is the independent variable. therefore 1 year is the x variable.

Using the prior info, we can form our equation to be: y = 855(1.06)^1 . From here we can solve for y.

Firstly, solve 1.06^1: y = 855(1.06)

Next, multiply everything, and your answer should be y = 906.30 . In this context, there will be $906.30 in your account after 1 year.
