write a rule to calculate the toilet cost C given the number of shirts n , for Tees and More.Tees and More quotes the price as $60 for the order fee and $5.50 per shirt

C=5.50 + 60

what is the price for the numbers of shirts found in the question 24 so that the price for either company is the same? Show all work and how do you solve it.

Plug your answer in to both equations that you came up with from #28 And # 27 c=8(18)+15 c=5.50(18)+60 - For both equations c equals 159

For what number of shirts will the price for either company be the same .Show all work and how do you solve it. The two equations that I made in the two questions before were c=$18.00n+15 C=$5.50n+$60

Set the two equations that you came up with equal to each other . 8n+15=5.50n+60 = n is 18
