Value of x=-225
Value of y=71.33
Explanation
:
2x/3-2x/5=-60 (1)
0.2x+0.9y=19.2 (2)
(2x*5-2x*3)/(3*5)=-60
(10x-6x)/15=-60
4x/15=-60
4x=15*-60
4x=-900
x=-900/4=-225
consider (2)
0.2x+0.9y=19.2
substitute the value of x in (2)
0.2*-225+0.9y=19.2
0.9y=19.2+45=64.2
y=(64.2)/(0.9)=71.33
Well, if you bought 10, it would be $2, but due to the decreasage, if you bought 8 it would be $2. The prrcantage decrease should be 20%.
