c)

You plan to sell each cake for $50. Write an equation that represents your total earnings, T, based on the price of your cake and how many you sell. Let x represent the number of cakes you sell.

* Use T and x as your variables

The equation that represents the total earnings (T) based on the price of the cake and the number of cakes sold (x) would be:

T = 50x

The equation that represents the total earnings, T, based on the price of each cake and how many are sold can be written as:

T = 50x

In this equation, T represents the total earnings, x represents the number of cakes sold, and 50 represents the price of each cake.

To write an equation that represents your total earnings, T, based on the price of your cake and how many you sell, you can follow these steps:

1. Determine the price of each cake, which is given as $50.
2. Assign a variable to represent the number of cakes you sell. In this case, we will use x.
3. The total earnings, T, will be equal to the price of each cake multiplied by the number of cakes sold. Therefore, the equation can be written as:

T = 50x

In this equation, T represents the total earnings and x represents the number of cakes sold.
