Graphed solution below
(You would place the dot on the first dot left of the 0, then continue to the left.)
From Walmart, you have to buy at-least= 50/8 = 6.25 = 7 [round-off to larger direction value ]
So, it would cost = 7 * 2.99 = $20.93
From Sam's club, you have to buy at-least= 50/12 = 4.16 = 5 [round-off to larger direction value ]
So, it would cost = 5 * 3.19 = $15.95
In short, Sam's club offers the better deal.
Now, we can spend our minimum expense, by buying 3 pcs. of bun from Sam's club and 2 from walmart.
In that case, it would cost = 3*3.19 + 2*2.99 = $15.55
Hope this helps!
Answer:
n = 24
p(a) = 10/24
p(b) = 15/24
[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer
[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24
If x were 40, then Y would be
A) 20
Third term a3 = 7 and 8th term a8 = 82
8th term - third term = 5d where d is the common difference:-
5d = 82-7 = 75
d = 15
so a2 = 7-15 = -8
and a1 = -8 - 15 = -23
a4 = 7 + 15 = 22
a5 = 37
a6 = 52
a7 = 67
