Answer:
no. of senior citizens=x
no.of other people=7-x
cost=30=k(7-x)+(k/2)x. k is the cost of a ticket
k(7-x+x/2)
k(7-x/2)-30=0
k=60/(14-x)
now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself
ie x= 2, k=5$
First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.
4x-2x-4x-8+4=-8
Then, put the numbers on one side.
4x-2x-4x=-8+8-4
Then, add it up.
-2x=-4
Then, solve for x.
(-2x)/(-2)=(-4)/(-2)
x=2
Hope that helps!
Answer:
uhhhh i think 82 but id.k lm.a.o
Step-by-step explanation:
4000 divided by 100 = 40
It will take her 40 weeks to reach 4000
However, 4000-1600=2400

The total of weeks she'll need to save will be 56.
She won't have enough money in 55 weeks.
