Answer:
x= 20 and the decreased value is 35-20=15
Step-by-step explanation:
percent increase = 6/14*100= 43
Percent decrease = 35-x/35*100
6/14*100=35-x/35*100
6/14= 35-x/35
6* 35= 14(35-x)
210= 490-14x
14x= 490-210
14x= 280
x= 280/14= 20
<span>The formula to the solution is as follows:
x = amount spent per person
d = drink
p = popcorn and
vc = veggie cup
this makes
(p+vc)/2 = they shared the poppcorn and the veggie cup and thus the sum musst be divided by the amount of sharing people which is two.
=> x = d + (p+vc)/2
And since there is no money mentioned for the movies (m) it is teh formula above.
If you would like to consider that costs too it would be:
x = m + d + (p+vc)/2</span>
