1 book = $15 / 6
= $2.50
Hope this helps :))

Answer:e=-10
Step-by-step explanation:
-2e-7=13
-2e=20
e=-10
75.41*11.5= 8.67
75.41+8.67=84.08
84.08*15%=12.61
84.08+12.61= 96.69
The total is $96.69
We let
a1 = first term
a2 = second term
a3 = third term
and so on
We are given with
a1 + a2 = 26
S5 (sum of five terms) = 35
The formula for the sum of terms is
Sn = (a1 + an) (n/2)
SO
35 = (a1 + a5) (5/2)
The formula for an arithmetic term is
an = a1 + d(n-1)
For
a2 = a1 + d
we know that
a1 + a2 = 26
Simply for a1, a2, and d. Then use the formula to get the other items asked.
A={x|x is an even while number between 0 and 2} = ∅ since there is no number between 0 and 2 that is an even whole number. So there is no number to be substituted for x, resulting in an empty set.
Hope that helps!
