Answer:

The single decimal multiplier is 0.9152

Step-by-step explanation:

Here, we want to write a single decimal number that would work as to decrease an original value by 12% and increase it also by 4%

Let the original value be x

12% = 12/100 = 0.12

So decreasing by 12% would be x-0.12x = 0.88x

Now this 0.88x, we shall increase it by 4%

4% is same as 0.04

Thus by increasing , we have;

0.88x + 0.04(0.88x)

= 0.88x + 0.0352x = 0.9152x

So the single factor we are multiplying by is 0.9152

Lena [83]

Answer:


Step-by-step explanation:

X+Y = 13

 

$18 + $22 = $258

OR

18X+22Y=258

 

18X + 22(13 - X) = 258

 

18X + 286 - 22X  = 258

 

286 - 4X  = 258

 

-4X= 258 - 286

 

-4X = -28

 

X= 7

Y=6

 7 of the X tour  packages & 6 of the Y tour  packages
