Brad and his mom went out for lunch and the bill came to $25.45. his mom wanted to leave a 18% tip. how much tip should they leave and what is the total bill

they would leave a tip of

$4.581 and their total bill would be $30.031

Step-by-step explanation:

Brad and his mom went out for lunch and the bill came to $25.45. His mom wanted to leave a 18% tip. This means that the amount of the tip that she wanted to leave is 18% of the bill that came. Therefore

Amount of tip = 18/100 × the bill that came.

Amount of tip = 0.18×25.45= $4.581

So they would leave a tip of $4.581

behind.

The total bill would be sum of the original bill + sum of the amount of tip that they want to leave behind. Therefore, it becomes

25.45 + 4.581 = $30.031

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.
