Answer:
D. Discount Deals Depot; $15.20
Why?
Lets do Big Bargain Bonanza first.
$8.00 would stay the same as it is for handling. The only number that would change is $1.25, it uses the the words PER pound for shipping.
Your equation would look like this with p being how many pounds Kanya is shipping:
$8.00+$1.25p
Now we just plug in the numbers.
$8.00+$1.25(6)=
$8.00+$7.50=
$15.50
The same games for Discount Deals Depot.
$9.50+$0.95(6)=
$9.50+$5.70=
$15.20
So in conclusion Discount Deals Depot; $15.20 is cheaper than Big Bargain Bonanza;$15.50
X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2
x = 9 -2y (from eq. 1)
Now substitute the value of x in the second eq.2
9-2y-y =6
-3y = -3
y =1
So,
x +2 (1)= 9
x= 7
