Step-by-step explanation:
Given:
No. = 78
Decrease% = 55%
To Find:
The result when 78 is increased by 55% = ?
Solution:
The result when 78 is increased by 55% = 78 - 55 x 78 / 100
The result when 78 is increased by 55% = 100 x 78 - 55 x 78 / 100
The result when 78 is increased by 55% = 78(100 - 55) / 100
The result when 78 is increased by 55% = 78 x 45 / 100
The result when 78 is increased by 55% = 3510 / 100
The result when 78 is increased by 55% = 35.1
Therefore,
The result when 78 is increased by 55% = 35.1

Answer:
Step-by-step explanation:
The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.
x + y = 14
The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.
8x +3y = 72
