Patrick took his parents to dinner and the bill was $70 plus 6% tax. if he left a tip of 15% of the total (food plus tax), what was the total cost of the dinner?

$85.33

Step-by-step explanation:

Bill: $70

Bill + Tax: $70 + $70(0.06)

              = $70 + $4.20

              = $74.20

Bill + Tax + Tip: $74.20 + $74.20(0.15)

                        = $74.20 + $11.13

                        = $85.33

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.
