A taxi charges a flat fee of $4.00 plus $2.25 per mile. How much will the taxi driver earn if he takes one passenger 4.8 miles and another passenger 7.3 miles? Explain your process.

So we need to figure out how much he earns. So, if he takes two passengers and he charges a flat fee of $4.00 the he already has $8.00. So now we need to figure out how much money he gets from 4.8 miles and 7.3 miles. So he charges 2.25 miles per hour. So to get the first evening we have to multiply 4.8 times 2.25 to get $ 10.80. To get the next passenger we have to multiply 7.3 times 2.25. When you multiply 7.3 by 2.25 is 16.425. So you add the totals together and get $ 13.225 or 13.22
