Question

A taxi ride costs $1.25 for the first quarter of a

mile and $0.30 for each subsequent quarter of a
mile.
a) A ride that costs $5.45 is how many miles
longer than a ride that costs $3.95? [Show
or explain the procedure used to obtain your
answer.]
b) If n represents the number of quarter miles
traveled and C represents the total cost of the
trip, which formula could be used to find C?
1) C = 1.25n
2) C = 1.25 +0.30n
3) C = 1.25 +0.30(n-1)
4) C= 1.25n+0.30n
c) Using your answer from part b, find the
value of C if n = 20.

Answer 1

Answer & Step-by-step explanation:

( Bold = Answers )

A = 5.45 - 3.95 = 1.5

1.5 / 0.3 = 5

5 x
`(1)/(4)` = 1.25 miles

B = C = 1.25 + 0.30 ( n + 1 )

C = C= 1.25 + 0.3 ( 20 - 1 )

= 1.25 + 0.3 x 19

= 6.95

We need to find the value of c which is: 6.95

Total cost of “ everything included “ : $6.95
