A taxi in new york city charges a flat fee of $3.50, plus $0.75 for every mile traveled. How much would a 6 mile taxi ride cost?
REY [17]
So, you start off with $3.50 you travle 6 miles every mile is 0.75 that means you would need to multiply 6 by 0.75.

6
0.75
it equals 4.5

So we have $4.50 we need to add $3.50 and in total $0.50 plus $0.50 would be a dollar + 3 dollars plus $4 would be 7 so 7 +1 is 8. and 8 is the answer.
