$\frac{22}{8}$ miles $2\frac{6}{8}$ miles

Work Step by Step

For the first 1/8 mile, the taxi will cost 1.75. After that, each 1/8 mile will cost .30. Take the total of 7.75 and subtract 1.75. This amount is for the first 1/8 mile. Then take the remaining cost of 6.00 and divide that by the cost of each 1/8 after that (.30). You get 20 1/8 miles. Add that to the first 1/8 mile and you get 21 1/8 miles or 22/8 miles or 2 and 6/8 miles. Miles=$\frac{1}{8}mi+20(\frac{1}{8})=\frac{21}{8}$ miles or $2\frac{5}{8}$miles Cost=$7.75-1.75=6.00$ $6.00\div.30=20$
