The sunglasses were originally priced at $ 21.
Given that Lori brought sunglasses and flip-flops at a half-off sale, to determine, if she spent a total of $ 21 on the two items, what was the original price of the sunglasses (taking into account that they both cost the same) will be you must perform the following calculation:
- 50 = 21
- 100 = X
- 100 x 21/50 = X
- 2100/50 = X
- 42 = X
Thus, the total price of both goods is $ 42, which, divided in half, results in $ 21 (42/2).
Therefore, the sunglasses were originally priced at $ 21.

First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)

aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
