1. A costume designer made 10 costumes that each used 5.8 yards of fabric. If she had 238.2 yards of fabric to start with, about
Zinaida [17]
 <span>You only need an estimate? Great. Think of the necessary material as 6 yards, so ten costumes would take 60 yards. Then think of the fabric on hand as 240 yards, so taking 60 yards away from that would leave [an estimated] 180 yards of fabric. 

For an equation, use: 

F" = F' - 5.8 C 

Where F' is the initial fabric stock, F" is the remaining fabric, and C is the count of costumes. 

In exact numbers, the formula works out to: 

F" = 238.2 - (5.8 * 10) 

F" = 180.2 

The estimate was very close. 

Good luck.</span>
