Multiply the cost of the game by the sales tax:
7% tax = 0.07
50 x 0.07 = 3.5
The tax would be $3.50
Solution is x=2 and y=-3
check the slopes since both are in slope int form
y=mx+b
m=slope
b=yint
we see one line has a slope of -2 and yint of 1
another one has a slope of 1/2 and yint of -4
y=-2x+1 and y=1/2x-4
1/2x-4=-2x+1
last one
Answer:
Option A) Combined, with a saving of x-y cents
Step-by-step explanation:
We are given the following in the question:
The rate to mail a package is x cents for first pound and y cents for each additional pound.

Weights of packages =
3 pounds and 5 pounds
Cost of combined package:
Total weight = 8 pounds

Cost of sending separately:

Difference between cost of sending the packages separately and combined

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents
Thus, the correct answer is:
Option A) Combined, with a saving of (x-y) cents
