5          |  150=30(5)    | $150
7          |  210=30(7)    |  $210
10        |  300=30(10)  | $300

Answer:

  • The  expression for the cost of renting a car d days is:

                [tex]c=30d[/tex]

  • The table can be made as follows:

    Number of days     Cost

          3                         90

          5                         150

           7                         210

          10                        300    

Step-by-step explanation:

It is given that:

The cost to rent a car is $30 per day.

Now, the expression which is used to represent the cost for renting a car d days is:

  [tex]c=30d[/tex]

where c is the cost of renting a car.

when d=3 we have:

     c=90

( Since, 30×3=90 )

when d=5

      c=150

( Since, 30×5=150 )

when d=7

     c=210

( Since, 30×7=210 )

when d=10

     c=300  

( Since, 30×10=300 )
