An art teacher needs to buy at least 60 brushes for her class. The brushes are sold in packs of 8. In which inequality does n represent the minimum number of packs the teacher needs to buy for her class?

Step-by-step explanation:

Given: An art teacher needs to buy at least 60 brushes for her class.

Number of brushes in each pack is equal to 8.

To find:  inequality where n represent the minimum number of packs the teacher needs to buy for her class

Solution:

Total number of brushes

Also,

Total number of brushes = where n represent the minimum number of packs the teacher needs to buy for her class

According to question,

part a: 1.08

part b: 27.59

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.
