16. Rihanna is the founder and CEO of Fenty Beauty on the release day of her new product, Flyliner Longwear Liquid Eyeliner, she sold 400 eyeliners
and averaged 50 eyeliner sales
per day after that.
Which equation models the number of Flyliner Eyeliners, f, did Rihanna sell after d days.
A. f = 400 + 50d
B. f = 50 + 400d
C. d = 50 + 400f
D. d = 400 + 50f

A. f = 400 + 50d

Step-by-step explanation:

First, let's understand each quantity/variable.

Now that we understand these variables, we can conclude that the equation would be A. f = 400 + 50d because to find the total, we have to add the 400 eyeliners sold at the beginning to the 50 eyeliner sales per day.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
