If Kerri goes to the fair and plans to ride 9 rides, how much will the event cost her? Answer: f = total cost c = number of ride tickets f = \$7 + \$0.50c cost for the fair and 9 rides c = 9 f = \$7 + \$0.50c f = \$7 + \$0.50*9 f = \$7 + \$4.50 f = \$11.50 the final answer is: the fair (with 9 rides) will cost Kerri \$11.50 Thanks for writing.
