Atruck can be ready for company a 420 dayplus $.30 per mile can we be charges $50 a day plus $.50 per mile to rent the same truck find the number of miles in a day at which the rental costs for a company a and company b same

it will take 1850 miles

Step-by-step explanation:

Let x represent the number of miles in a day at which the rental costs for a company A and Company B same.

Let y represent the total cost of renting the truck for x miles with company A.

Let z represent the total cost of renting the truck for x miles with company A.

Company A charges $420 a day Plus $.30 per mile. This means that

y = 420 + 0.3x

Company B charges $50 a day plus $.50 per mile to rent the same truck. This means that

z = 50 + 0.5x

To determine the number of miles in a day at which the rental costs for a company A and Company B same, we will equate y to z. It becomes

420 + 0.3x = 50 + 0.5x

0.5x - 0.3x = 420 - 50

0.2x = 370

x = 370/0.2 = 1850 miles

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.
