Kyle's birthday party in 2007 cost $d$ dollars per person and $p$ people attended. in 2008, the cost per person doubled and the number of people attending the party also doubled. what is the ratio of the total cost of the party in 2007 to the total cost of the party in 2008?

The  ratio of the total cost of the party in 2007 to the total cost of the party in 2008  = 1: 4

Step-by-step explanation:

It is given that Kyle's birthday party in 2007 cost $d$ dollars per person and $p$ people attended.

Then , the total cost of the party =  Cost per person x  Number of people attended.

For 2007, Total cost = d x p = dp              (1)

In 2008, the cost per person doubled and the number of people attending the party also doubled.

i.e.  Cost per person = 2d

Number of people attended = 2p

For 2008, Total cost = 2d x 2p = 4dp        (2)

From (1) and (2) , the ratio of the total cost of the party in 2007 to the total cost of the party in 2008 will be :

Cancel pd from the numerator and the denominator , we get

Hence, the  ratio of the total cost of the party in 2007 to the total cost of the party in 2008  = 1: 4

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.

you divide them and then you get the answer i took this class this year
