Answer:
63-9b
Step-by-step explanation:
9(7-b)
=9×7-9×b
=63-9b
Each pound 4.20/2 = $2.10
5 pounds will cost + 2.10 x 5 = $10.50
131.25 miles.
If 1 inch actually equals 25 inches, then you can just multiply 5.25 inches by 25, and because 1 in is equivalent to 25 miles, then your final answer will be in miles
