Question

Business and finance. A store has T-shirts on sale at 2 for $5.50. At this rate, what
do five T-shirts cost?

Thank you for using the Jiskha Homework Help Forum. Why not find out what one shirt costs first? Divide $5.50 by 2 and you get $2.75, which is the price for one shirt. Now Take $2.75 times 5 = $13.75.

There is also another way to do this. Take $5.50 times 4 and then add the $2.75 which is half the $5.50. The price comes out the same = $13.75.
