the cost of renting a scooter is represented by 3j+5. Write and simplify an expression that represents the cost of renting 6 scooters.

Simplified expression that represents the cost of renting 6 scooters is 18 j +30Step-by-step explanation:Given data: The cost of renting of a scooter is represented by 3j +5 So, from that, we can say in general, The cost of renting of n scooters is represented by                                    [tex]n \times(3 j+5)[/tex]But according to given, the value of n is 6. i.e. to find the cost for six number of scooters. We can calculate now as follows So, the cost of renting of a scooter is represented by                                    [tex]6 \times(3 j+5)=18 j+30[/tex]
