Brainstorm alison sets aside $55 each month to spend on books and cd .if she spend c dollar on cds ib a given month she may spend b dollar on books where c+b =55.graph the equation and use the graph to estimatw the amount alison may soend on book in march if she spend $30 on cds

For a better understanding of the solution/explanation given here please go through the graph in the file attached.

It is given that Alison sets aside $55 each month to spend on books and cd. Thus, the guiding equation that will define this situation has been given as:

Where b is the amount for books and c is the amount for cd.

In terms of books the above equation will become:

This equation has been graphed in the attachment where the x axis is the axis for c (CD) and the y axis is the axis for b (books)

Now, it has been given that Alison has spent $30 on CD. Therefore, as can be seen from the graph, the vertical line is that of c=30 and it intersects the b=55-c at (25,30), thus, the amount Alison may spend on books in march is $25.

b. 2 and 4

step-by-step explanation:

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.
