Answer 1

To get the average cab fare cost reported for five, we sum up all the cost first. 
For Tuesday and Wednesday, the total cost would be 2($7.75) which is equal to $15.5. For Monday and Thursday, the total would be $12.6. Then lastly for Friday that would be $7.0. Adding up all the costs and dividing the sum by 5 (number of days) the answer would be $7.02. 
Thus, the average cab fare cost is $7.02.
