Mike saves $42 a week for 7 weeks. during his 8-day vacation, he plans to spend $8.25 each day for snacks. which expression shows how much money he will have left?
(42 ÷ 7) – (8 • 8.25)
(42 • 7) – (8 • 8.25)
(42 • 7) + (8 • 8.25)
42 • 7 • 8 • 8.25

The correct option is:  (42 • 7) – (8 • 8.25)

Step-by-step explanation:

Mike saves $42 in each week.

So, the amount he saves in 7 weeks =

He plans to spend $8.25 each day for snacks during his 8-day vacation.

So, the amount he will spent in 8 days =

Thus, the amount of money he will have left =

6e14 is the answer.

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.
