Edgar ran eee meters per second, and mathieu ran mmm meters per second. the boys ran for ttt seconds.
the expression t(m-e)t(m−e)t, left parenthesis, m, minus, e, right parenthesis describes how many more meters mathieu ran than edgar ran during that time. we can also use the expression tm-tetm−tet, m, minus, t, e to represent the same quantity.
match each amount in the situation with the expression that represents it.\

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.

the answer would be  

a.
