A company that makes scarves has many different styles and colors that people can order. The company keeps track of the number of each style, color combination they make, and the average sale price for the scarves having that combination. They create a scatter plot using the data with the number of scarves along the x-axis and the average price per scarf, in dollars, along the y-axis. Q3.1) The data in the graph suggest a linear association. Which of the functions best
represents the equation of the line of best fit?
A. y = -225x + 1,124
B. y = -0.004x + 5
C. y = -x + 5
D. y = 0.01x + 5

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
