Answer:
It is better to to buy from At Food Lion
Step-by-step explanation:
At Harris Teeter: 7 picture frames cost $15
Cost per picture frames = Total cost of picture frames / number of picture frames
= $15 / 7

= $17 / 9
= $1.89 per picture
The cost of pictures frames Amat Food Lion is cheaper than at Harris Teeter
{{{ THE BOLDED CHARACTERS SHOULD BE SMALL. }}}
SEQUENCE: 6, 18, 54, 162
18/6 = 3
54/18 = 3
162/54 = 3
then, r (common ratio) = 3
_________________________________________
RECURSIVE RULE: r = 3
an = a(n - 1) × r [formula]
ANSWER: an = a(n - 1) × 3
ITERIATIVE RULE: r = 3, a1 = 6
an = a1 × r^(n - 1) [formula] [ ^(n-1) is an exponent]
ANSWER: an = 6 × 3^(n - 1)
19
Add up all the numbers:
3,2,2,2,1,1,1,4,2,1
Then you get 19.
Or you can say it as
3^2 + 2^4 + 1^4 + 4
25
