Answer:
The cost price was 500.
Step-by-step explanation:
Let x be the original price.
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.

Step-by-step explanation:
Note there is a common ratio r between consecutive terms in the sequence, that is
r = 80 ÷ 320 = 20 ÷ 80 = 5 ÷ 20 = 1.25 ÷ 5 = 0.25
Thus the sequence is geometric.
A recursive rule allows a term in the sequence to be found by multiplying the previous term by r, thus
= 0.25
with a₁ = 320
