Answer:
5
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
The expression inside the summation is
4 ← the nth term of a geometric sequence
with a = 4 and r = , then
=
=
= ( )
=
= 5
The rate that is equivalent is 42 miles over 3 gallons
42/3=14
14:1=14 42/3=14
Answer:
dollars per mile
$0.90 per mile
Step-by-step explanation:
Since you are interested in the price of a 42-mile ride, you need a unit cost of dollars per mile. The time the trip takes does not matter.
unit price in dollars per mile = (price)/(number of miles)
unit price = $50.40/(56 miles) = $0.90/mile
Answer the unit price is $0.90 per mile
