Answer:
Step-by-step explanation:
We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.
Let x= Number of tiles
y=Area covered by Felicia's tile





The ratio of x and y remains constant.Therefore, it is direct proportion .
Equation of direction proportion is given by

Where
k=The value of ratio of x and y
x and y are variables
We have k=9
Substitute the values in the equation
Then, we get



This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.

The profit from sales if the price of the T-shirts were $15 a pieces is $28.
Step-by-step explanation:
Given : The function
is used to determine the profit on T-shirts sold for x dollars.
We have to find the profit from sales if the price of the T-shirts were $15 a pieces.
Consider the given profit function 
For the profit, if the price of a t-shirt is $ 15
Put x = 15, we have,

Simplify, we have,

Also, 
Thus, we get, The profit from sales if the price of the T-shirts were $15 a pieces is $28.
