who are the reference persons*

You're told that the fabric costs $11.49 per yard, and that Yvette buys 9.3 yards. That means you need to multiply the cost per yard ($11.49) by the total number of yards (9.3) to get the total cost.
(Think of multiplication as repeated addition and that you're repeatedly adding $11.49 for each yard you have)!

Since you're estimating, you can round $11.49 to $11.50. You can also round 9.3 to 9 yards.
