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.

The equation that represents your total earnings, T, based on the price of your cake and how many you sell is:

T = $50 * x

The equation that represents your total earnings, T, based on the price of your cake and the number of cakes you sell, represented by x, is:

T = $50 * x

To write an equation that represents your total earnings, you need to multiply the price of each cake by the number of cakes sold. In this case, the price per cake is $50, and the number of cakes sold is represented by x.

So, the equation that represents your total earnings (T) would be:

T = 50x
