A certain taxi company charges $3.10 for the first 1/5 of a mile plus $0.40 for each additional 1/5 of a mile. What would this company charge for a taxi ride that was 8 miles long?

A certain taxi company charges $3.10 for the first 1/5 of a mile plus .40 for each addtional 1/5 of a mile. What would this company charge for a taxi ride that was 8 miles long?

A. 15.60 B. 16.00 C. 17.50 D. 18.70 E. 19.10

so 3.10 for first 1/5mile and .4* so how many 1/5's in 7 and 4/5 miles? well 5 per 7 and 4 for 4/5 So should be.

A certain taxi company charges $3.10 for the first 1/5 of a mile plus .40 for each addtional 1/5 of a mile. What would this company charge for a taxi ride that was 8 miles long?

A. 15.60 B. 16.00 C. 17.50 D. 18.70 E. 19.10

How many 1/5 miles does 8 miles contain?
= 8/(1/5) = 40
Charge for first 1/5 mile = 3.10
Charge for remaining 39 1/5 miles = 39*.4 = 15.6
Total charge = 15.6 + 3.10 = 18.70

A certain taxi company charges $3.10 for the first 1/5 of a mile plus .40 for each addtional 1/5 of a mile. What would this company charge for a taxi ride that was 8 miles long?

A. 15.60 B. 16.00 C. 17.50 D. 18.70 E. 19.10

= 3.10 + (8 - 0.2) 0.4/0.2 = 3.10 + 15.6 = 18.7

Dear Gmatiger

Can you help me to understand why the result must be divided into 0.2?
I am confused!
Thanks,

Dear Gmatiger

Can you help me to understand why the result must be divided into 0.2? I am confused! Thanks,

it is just an unitary method:

The cost per 1/5 (0.2) miles is 0.4 beyond first 1/5 (0.2) miles.
so 0.2 miles costs 0.4, then how much 1 mile costs? 2. how 0.4/0.2 = 2.
so 1 mile costs 2, then 7.8 (=8-0.2) miles cost 7.8x2 = 15.6

I am confused because 1/5 of a mile is 1.6. 1/5 of 8 miles is 1.6 and then there are 6.4 miles left?

I don't get it?!

I was stuck at the same place and took me more than a 20 mins to figure it out that the 1/5 is actually a 0.2 miles NOT 1.6 miles. If it is a 1.6 miles, if you try to add 1.6 five times, you won't be able to get 8miles..

I don't understand the calculations for this problem I'm getting 3.12 when I calculate 7.8 * 0.4

1/5 miles = 0.2 miles.

The cost of 8 miles long ride would be $3.10 for the first 0.2 miles plus (8-0.2)/0.2*0.4 = $3.1 + $15.6 = $18.7.

I am confused because 1/5 of a mile is 1.6. 1/5 of 8 miles is 1.6 and then there are 6.4 miles left?

I don't get it?!

I just find the problem about the 1.6 in this question, it says 1/5 of a mile, not 1/5 mile of a mile you see, that's why we do not need to use 8 mile divided by 1/5
