There is a new quilting notion I would like to purchase. It comes in two sizes. I will use a proportion to determine how much of a savings the larger size will be. The wonder clips come in packaged of 10 for $5.49 or 50 for $24.99.

To do a price comparison I will figure out the unit cost for 50 clips at the $5.49 price for 10.

My equation: 5.49 = x 5.49 x 50 = 10x 274.5 = 10x 274.5 = 10x $27.45

10 50 10 10

Answer: I will purchase the 50 count package because the savings is $27.45 – $24.99 = $2.46 plus the 50 count package comes with a free storage container.

I have just started a new knitting project. The sock pattern instructed me to knit for 8 ½ inches. I knit 5 rows and it measures ½ inch. How many rows will I have to knit to reach 8 ½ inches?

My equation: 5 = x 5 x 8.5 = .5x 42.5 = .5x 85 = x

.5 8.5 .5 .5

Answer: I will need to knit 85 rows to reach 8 ½ inches.
