You changed the pricing for renewals of your product. your previous renewal rate was $250. your income from renewals was $750,000 this year. the new renewal rate is twice the old rate. you have 2500 customers total. show calculator select the best answer how many customers paid the old rate and how many paid the new rate?

2000 customers paid the old rate and 500 customers paid the new rate.

Step-by-step explanation:

The new renewal rate is twice the old rate. That is dollars

Let x be the old rate.

Let y be the new rate.

As given: Your income from renewals was $750,000 this year.

So, we have the following equation:

or  .....(1)

And total you have 2500 customers, so we get the following equation:

     .....(2)

Deriving from (2) and substituting in (1)

=>

y = 500

x = 2000

Hence, 2000 customers paid the old rate and 500 customers paid the new rate.

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.
