How to solve these kind of problems? The Vindale Tigers are having team shirts made. One option is to pay Sophia's Tees a $37
setup fee and then buy the shirts for $7 each. Another option is to go to City Printing, paying
$41 for a setup fee and an additional $5 per shirt. The team parent in charge of the project
notices that, with a certain number of shirts, the two options have the same cost. How many
shirts is that? What is the cost?
