Mrs. Markum took her family to a restaurant for dinner. The bill was $39.50. She had a 15% off coupon, and left a 20% tip on the original bill (before the
coupon). How much did Mrs. Markum pay?

$41.47

Step-by-step explanation: .15 x 39.50 = 5.925 (round up to 5.93), 39.50-5.93=33.57, .20 x 39.50 = 7.90, 33.57 + 7.90 = $41.47

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.
