Last year, Luisa planted 450 tulip bulbs. This year she planted only 4-- tulip bulbs. Which represents the percent decrease in the nuymber of bulbs planted?

(450 - 4)/450 = ?

The answer does not fit your number choices.

Are there numbers in the place of the dashes? If so, substitute that complete number for the 4 in the equation above.

I hope this helps. Thanks for asking.
