Final answer:
The cost of a 12-mile taxi trip is calculated by adding the cost for the first mile, which is $1.4, to the cost of the remaining 11 miles at $1.05 per mile, resulting in a total cost of $12.95.
Step-by-step explanation:
To determine the cost of a 12-mile taxi trip, we need to consider the cost for the first mile and the cost for each additional mile. The cost for the first mile is $1.4. Since the total trip is 12 miles, we have 11 miles that are charged at the rate for additional miles, which is $1.05 per mile.
Now, let's calculate the cost for the additional miles: 11 miles × $1.05 per mile = $11.55. Adding the first mile cost to this amount gives us the total cost of the trip:
The cost of a 12 mile trip can be calculated by multiplying the cost of the first mile by 1 and the cost of each additional mile by 11, since there are 11 additional miles. Therefore, the cost of a 12 mile trip would be:
Cost of first mile: $1.4
Cost of additional miles: $1.05 x 11 = $11.55
Total cost: $1.4 + $11.55 = $12.95
Total cost = Cost for the first mile + Cost for additional miles
Total cost = $1.4 + $11.55
Total cost = $12.95
So, the cost of a 12-mile taxi trip is $12.95.
