Question

Below are given functions representing two ways of transport:

$\text{Transport A: fair per 1 mile is}\$\text{15 plus}$
$\text{an additional charge of}\$\text{5}.$

$\text{Transport B:}$


Which of the following transport ways has a lower charge to travel 20 miles?

• A. Transport B
• B. Both are best for transport
• C. Transport A
• D. None

Answer 1

The correct option is C Transport A

For Transport A:

$\text{Cost for every one mile =}\$15$

$\text{Additional charge =}\$5$

If we need to travel 20 mile, then the total charge will be:

$20\times 15+5=\$305$

For Transport B:


Writing the above information in the form of a table, we get:

Distance (in mi)	Price (in $)
1	20
5	100
10	200
15	300
20	400

$\text{So, the total cost for to travelling 20 mile is}\$\text{400}$

Therefore, transport A is better to travel as it costs less to travel 20 miles.
