We want to find how much the extra fabric costs. To do so, we will find the unit rate, which is the unit price of fabric, and multiply it by 2 yards. We know that Kenji buys 3 yards for $ 7.47. Let's write a rate to show this situation. Since we want to find the unit price, we will $ 7.47 in the numerator.
$ 7.47/3yards
A unit rate is a rate that has been reduced to a denominator of 1 unit. In this case, the unit rate is the unit price of fabric. Let's find the unit rate! For simplicity, we will ignore the units.
We found the unit rate!
$ 7.47/3yards =$ 2.49/1yard
As we can see, the unit price of fabric is $ 2.49 per yard. Now we can multiply the unit rate by 2 yards.
$ 2.49/1 yd * 2 yd = $ 2.49 * 2 = $ 4.98
We found that the extra fabric costs $ 4.98.
