Answer:
suppose that r = 50%=0.5,
t =10 years and P= 100, find A?
A=100(1+(0.5)(10))=600
suppose t =10 yrs, r=50%, A=600, find P?
P=600/((1+(0.5)(10))=100
suppose t =10 yrs, r=50%, A=600, P= 100 find r?
r= (600-100)/100(10)=500/1000=0.5=50%
suppose r=50%, A=600, P= 100 find t?
t= (600-100)/100(0.5)=500/50=10 yrs
c = number of children tickets sold
a = number of adult tickets sold.
we know that 178 total tickets were sold, thus whatever "c" and "a" are, c + a = 178.
the price of a child ticket is $5.4, so the price for all "c" tickets must be 5.4c.
the price of a adult ticket is $9, so the price for all "a" tickets must be ac.
we also know the total sales for all tickets combined is $1310.4, so then 5.4c + 9a = 1310.4.
