Plz ! a store can purchase t-shirts for $7 each. it has fixed costs of $2500. each t-shirt is sold for $18

a. write a linear equation for both cost and revenue.

b. graphs both the cost line and the revenue line.

c. determine the break-even point

d. if the store wants to make a profit of $2000, how many t-shirts must it sell?

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

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.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
