Answer:

The total cost of redecoration is £66, that is less than £75. Tenant can decorate the room for the budget set.

Step-by-step explanation:

Lets start calculating the areas of shorter and longer walls.

The area of shorter wall is

2.65m*2.98m=7.897m^2.

The area of longer wall is

3.94m*2,65m=10.441m^2.

Together the area of one long and one short wall is

7.897m^2+10.441m^2=18.338m^2.

The area to be painted ( one short and one long wall) is 18.338m^2 that is less than 30m^2, and hence only one tin of paint is needed (costs £16).

If there is assumed that the sheets of wallpaper must be whole from floor to ceiling, the calculations are following.

We get from one roll

10m/2.65m=3.77 sheets; we can use only 3 of them

The width of the walls is 3,94m+2,98m=6,92m,

and division gives 6.92m/0.52m=13,3... .

Hence it requires 14 sheets, that is 5 rolls of wallpaper.

Wallpaper costs 5*£10=£50 and altogether it is needed £50+£16=£66 to redecorate the room.

Which is better: having a stock that goes up 30% on Wednesday than drops 20% on Thursday, or a stock
finlep [7]

Step-by-step explanation:

  • If the stock goes up 30%, it's multiplied by 1.3.

The reason is that  x + .3 \times x=1.3\times x

  • If the stock goes down 20%, it's multiplied by 0.8

The reason is that x - .2 \times x = 0.8 \times x

  • If the stock goes down 30%, it's multiplied by 0.7

The reason is that x - .3 \times x = 0.7 \times x

  • If the stock goes up 40%, it's multiplied by 1.4.

The reason is that  x + .4 \times x=1.4\times x

So

If you increase it by 30% and then drop it by 20%, it means you are multiplying it by 1.3 and then multiplying it by .8. In other words:

1.3 \times 0.8=1.04

So, the net gain is = .04

Assume the original value = 500

Increase it by 30% and it becomes 650

Decrease 650 by 20% and it becomes 520

So, the net gain = 20

Verification:

500 \times .04=20

And

If you drop it by 30% and then increase it by 40%, you are multiplying it by .7 and then multiplying it by 1.4. In other words:

.7 \times 1.4=0.98

So, the net loss is = 1 - 0.98 = .02

Assume the original value = 500

Decrease it by 30% and it becomes 350.

increase 350 by 40% and it becomes 490.

So, the net loss is = 10

Verification:

500 \times .02=10

Keywords: stock, loss, gain
