The admission to a local carnival is $6.50 per person and $2.50 for each ride. jenna wants to know much it will cost her to ride a certain number of rides at the carnival. which equation can she use to create a table with this information (where  p  is the number of persons,  r  is the number of rides, and  t  is the total cost of admission and rides)?   6.50p  + 2.50 =  t6.50 + 2.50r  =  t6.50r  + 2.50 =  t6.50 + 2.50p  =  t
