(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
20% off means you paid only 80% of the original price.

First divide 3.7 by 0.006
Which is 616.666
The last 6 is the thousandths place. If it is 5 or bigger then the number to the left is rounded up. If its lower than 5 you round down
Since 6 is over 5 we tound up
616.67
