x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.

Step-by-step explanation:
P(9)=0
The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058
The given geometric sequence is:
4, -12, 36, -144
The first term, a = 4
The common ratio,

Since we are looking for the sum of the first 10 terms
The number of terms, n = 10
The sum of the first n terms of a geometric sequence is given as:

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058
