Alexander is going to an amusement park. The price of admission into the park is $15, and once he is inside the park, he will have to pay $3 for every ride he rides on. How much money would Alexander have to pay in total if he goes on 5 rides? How much would he have to pay if he goes on rr rides?

Answer :

Given :

Admission price , A = $15 .

Price of each ride , p = $3 .

Number of rides , r = 3 .

To Find :

Total money spend if he goes on 5 rides and for r number of rides .

Solution :

Let , total amount paid is P .

First we find the general equation :

[tex]Total \ amount = Admission\ Fee - r\times ( Fee\ per\ ride )[/tex]

[tex]P=15+3r[/tex]

Now , for r = 5 , total price is :

[tex]P=15+3\times 5\\\\P=15+15=\$30[/tex]

Hence , this is the required solution .
