Hi!
<h3>Divide each part of the number by 8. </h3>
------------------------------------
no.
------------------------------------
<h3>Yes! 8 times. </h3>
8 * 8 = 64
71 - 64 = 7
Carry the seven to the 2...
------------------------------------
<h3>Yes! 9 times. </h3>
8 * 9 = 72
<u>72 - 72 = 0</u>
<h2>The answer is 89</h2>
Hope this helps! :)

This is an arithmetic sequence with first term (a) = 11, number of terms (n) = 57, sum of nth term (Sn) = 19,779.
Let the amount of money she saved more each month be d, then
Sn = n/2(2a + (n - 1)d)
19,779 = 57/2(2(11) + (57 - 1)d)
19,779 = 28.5(22 + 56d)
19,779 = 627 + 1,596d
19,779 - 627 = 1,596d
d = 19,152/1,596 = 12
Therefore, she saved $12.00 more each month.
Width = w
length = 11w
Pythagoras theorem
a^2 + b^2 = c^2
Let's say the width is a, the length is b, and the distance between corners (call it d) is c
w^2 + 11w^2 = d^2
Collect like terms,
12w^2 = d^2
Simply
12w = d
