An expression for the cost will be 50+100n, where n is the number of cavities.
The correct answer is B) 775
Why 775? Because Assume the series continues.
400+200+100+50+25=775
I hope this helps.
Have a great day. :)
For this case we have that the original value of the car is:
m dollars
For the following year we have the value is:
((100-15) / (100)) m
Rewriting we have:
((85) / (100)) m
0.85m
Answer:
the value of his car the year after the car is worth m dollars is:
B.f (m) = 0.85m
Amount spent on the last call = $25 - $22.04 = $2.96 = 296 cents
Number of minutes used for last call = 296 / 8 = 37 minutes.
